Artisanal Cannabis Extraction – An Interview with Precision Founder Nick Tennant

By Aaron Green

Cannabis and hemp derived concentrates are a rapidly growing product category. Formed by extracting cannabis using a variety of methods including ethanol, butane hash oil and CO₂, concentrates find their way into consumer packaged goods as ingredients for infused products or as stand-alone products such as resins, rosins, distillates and hash.

Precision Extraction Solutions (Precision) was founded in 2014 to provide equipment and services to cannabis and hemp processors. In October 2021, Agrify (NASDAQ: AGFY) purchased Precision in a $50M cash and stock deal. The move positions Agrify to offer end-to-end infrastructure solutions for cannabis cultivators and processors.

We interviewed Nick Tennant, SVP of Innovation at Precision, now a division of Agrify. Nick founded Precision after seeing a need for quality equipment in concentrate processing. Prior to Precision, Nick was involved in a vertically integrated cannabis business in Michigan where he gained experience in cultivation, extraction and retail.

Aaron Green: How did you get involved in the cannabis industry?

Nick Tennant: I’ve been in cannabis about 17 years now. I had family in Colorado and California who I started to interface with around 2006. Around 2008, Michigan passed their cannabis law, and we were one of the first businesses to get licensed. The subsequent five years from that law getting passed, up to 2013, I did pretty much everything in terms of commercial cannabis – cultivation, retail, edible manufacturing, you name it. Concentrates didn’t really exist in a meaningful way; the products definitely were there, but the technology wasn’t. I looked at technology at the time and it was very primitive, so we made a shift to focusing on concentrates. We launched Precision in 2014 and we basically shot out of a cannon, doing a million dollars in sales in our first 90 days. Since then, we grew the company up to 60 employees and substantial amounts of revenue. We sold Precision to Agrify in October of this year.

Green: Tell me about that transition from a cannabis products company to an equipment manufacturer.

Tennant: It was a gradual transition. As I started to see the extraction niche expand, I really started to put more time and resources into it. When we launched Precision and were met with such success in just the first 90 days, I knew that I had to abandon everything else I was doing to focus on this. My former partners took over the businesses, like the grows. We worked out individual circumstances regarding how I was going to leave those businesses and focus full time at Precision.

Green: So, big news recently with the acquisition, congratulations on that! Tell me about Agrify and why a deal with Agrify made sense to you.

Tennant: The strategic rationale is that we are providing an end-to-end infrastructure solution. They have the horticultural aspect, an excellent public vehicle, and plenty of cash on the balance sheet to continue to scale the business and acquire additional constituents within the cannabis infrastructure. Getting to the point where you can exit the businesses, it’s a long road, and our business is very niche. We were seeking to partner with t a bigger player in the industry with more resources that would help us to scale what we were trying to do, and Agrify was the perfect fit.

Green: You’ve got several areas of focus at Precision ranging from ethanol extraction, distillation, and butane hash oil (BHO) extraction. Where are you focusing the business going forward?

Tennant: Going forward we want to provide that end-to-end one-stop shop infrastructural solution for any cannabis products company. We want Agrify to become the dominant and fastest growing player in the cannabis industry for infrastructural solutions, whether that’s horticulture or extraction. We’re continuing to expand our product portfolio into other niches so that if you’re building a cannabis facility, you only need to come to one company and the process is as simple as possible.

Green: What kinds of products are you seeing the consumer gravitate towards?

Tennant: I think that cannabis will remain to be very artisanal because of the uniqueness of the plant. If you look at similar industries, I could compare it to craft beer or winemaking. I think that hydrocarbon and water hashes will continue to play a substantial role. I also think that ethanol and distillate-based products will hold market share just like the Budweiser and Kendall Jacksons of the world.

People love the native sort of essence of the plant, that this is a plant sort of bestowed upon us by the universe with all these unique healing and restorative properties. I think that trying to capture those properties and that native essence of what’s going on within the genome of the plant and translate that into a product is going to be the theme that continues to dominate, and I think that for several reasons. For the same reason somebody will go to Whole Foods, and they’ll buy the local organic grown fruit or vegetables, people are going to gravitate towards artisanal cannabis products. People that consume cannabis, generally speaking, are more naturalistic or homeopathic than most.

Green: Precision has technology for a range of extraction methods where the focus has been on cannabis. Are you seeing any new markets outside of cannabis?

Tennant: Yes. We’ve dealt with varieties of different botanical extraction companies over the years, but they’re a very small segment of our business. We’re a cannabis business. Non-cannabis extraction may make up less than 1% of our business so it’s very small.

Green: What trends are you following in the cannabis industry?

Tennant: Consolidation, I would say, is a big one. MSOs are consolidating and buying up the small players. The second major trend is regulation, and what’s going on in DC. Beyond that, you obviously have new states coming online, shifting consumer trends, things like that. I would say these last two are less impactful from a macro standpoint, but nonetheless, still things that we follow.

Green: Following up on consolidation, do you see a demand for larger systems now?

Tennant: I’d say 95% of what we do is under 2000 pounds a day, which we consider artisanal. You’re not going to see large scale production consolidation because you have fragmentation by state. It would be most efficient for a cannabis manufacturer to manufacture everything in one location but it’s just not possible with the state laws. It’s very fragmented. Somebody like a Trulieve might have 20 different manufacturing operations, all running similar processes. Perhaps we will see more upon national legalization and the opening of state borders.

Green: What in your personal life or in the cannabis industry are you most interested in learning about?

Tennant: I am constantly learning. That’s just how my brain is, and the type of person that I am. I’m interested in a variety of topics, but I think I’m most interested in how capital markets are going to materialize and substantiate around the federal legalization because we’re in this weird space of cannabis. It’s weird, because you have a boom industry that’s generating massive amounts of revenue and massive amounts of tax dollars, but you must remind yourself that there is no real liquidity in this market, meaning you can’t finance things. A typical cannabis company that wants to go out and get capital is getting rates between 16 to 18%. There’s just a capital restriction since cannabis is a Schedule I substance, and these large lenders don’t want to play into that.

The question in my head and the big catalyst for the entire industry is: what happens when we get a descheduling, decriminalization and/or legalization on a federal level? How does that affect the large funds sentiment to deploy this zero-interest rate capital that we’re seeing in the rest of the world? We’re seeing it in mortgages. We’re seeing it in every aspect of the world. There’s free money printing, but it’s not flowing into cannabis because those federal laws are prohibiting it as such. Ultimately, as more infrastructure comes online, these companies are not going to have to scrape by to build a $3 million lab. They can finance it at a reasonable interest rate, and the infrastructure can come online.

That’s going to be better for the consumer. There will be more infrastructure, more products, more research and development, more retail locations. Everything gets better, more convenient, and more robust. I would think that finance interest rates are the largest lever within the industry right now, and because of that, you’ll likely see cannabis capital markets go pretty crazy when legalization comes around.

Green: Okay, great. That concludes the interview.

Tennant: Thanks, Aaron.

Canadian Lab Offers Vapor/Smoke Analysis

By Cannabis Industry Journal Staff

No Comments

According to a press release sent out last week, Complex Biotech Discovery Ventures (CBDV) has expanded their testing capabilities considerably with the new addition of a vapor/smoke analyzer. CBDV is a licensed cannabis and psilocybin research laboratory embedded in the University of British Columbia, led by CEO Dr. Markus Roggen.

Dr. Markus Roggen, Founder of Complex Biotech Discovery Ventures (CBDV)

The ability to analyze vapor and smoke is a relatively novel concept for the cannabis space, but has been utilized by the tobacco industry for years now. In the early days of adult-use cannabis legalization in the United States, stringent testing regulations for contaminants like pesticides were adopted out of a fear for what would happen when consumers ingest toxic levels of contaminants.

One of the common refrains iterated throughout the industry over the past ten years was that there just wasn’t enough research on how different contaminants affect patients and consumers when burned and inhaled. We still don’t know too much about what happens when someone smokes a dangerous pesticide, such as myclobutanil. Beyond just contaminants, the new technology allows for companies to measure precise levels of cannabinoids in vapor and smoke, getting a more accurate reading on what cannabinoids are actually making it to the end user.

This new development coming from our neighbor to the north could lead to a breakthrough in the cannabis lab testing and research space. CBDV claims they can now analyze cannabis material with a much more in-depth analysis than basic compliance testing labs. The new technology for analysis of smoke, vapor, plant material and formulations allows companies to thoroughly understand their materials in each stage of the product formulation process, all the way to product consumption.

Beyond just smoke and vapor analysis CBDV also offers NMR spectroscopy, metabolomics, nanoparticle characterization, computational modeling and other testing services that go far beyond the traditional compliance testing gamut.

“Our new services offer comprehensive insights into plant material, extracts, end-products and even the smoke/vapor by using state-of-the-art analytical instruments,” says Dr. Roggen. “By understanding the chemical fingerprint of the material, cannabis producers can eliminate impurities, adjust potencies, and optimize extraction processes before wasting money and resources on producing inconsistent end products. As a chemist I am really excited about adding NMR and high-res mass spectroscopy to the cannabis testing offerings.”

The Craft of Extraction: Like Beer Making, It’s All About Control

By Jeremy Diehl

No Comments

Any brewmaster from the more than 7,000 U.S. craft breweries will tell you one of two things: That their art is a science, or that their science is an art. The answer might depend upon the brewer’s individual approach, but a combination of experience, process, precise measurement and intuition is exactly what’s required to create great beer. In a very similar way, the cannabis industry has its own version of the brewmaster: Extraction technicians.

A cannabis extraction technician deploys knowledge from multiple science disciplines to apply industrial solvents, heat and pressure to plant matter through a variety of methods with the aim to chemically extract pure compounds. Extraction techs use their passion for the cannabis and hemp plants, combined with chemistry, physics, phytobiology and chemical engineering to help create a result that’s not quite art, but not quite completely science. By manipulating plant materials, pressure, heat and other variables, the extraction technician crafts the building block for what will become an edible, tincture or extract.

Similarly, brewmasters use their knowledge of multiple science disciplines like chemistry and microbiology, as well as different brewing processes and a variety of ingredients to develop creative recipes that result in consistent, interesting beers. The brewmaster’s work is both science and art, as well. And they also manipulate plant materials, pressure, heat and other variables to achieve their desired results.

Author Jeremy Diehl collects cannabis extract from equipment for testing

“I would certainly consider brewing to be an art and a science, but it takes a very disciplined approach to create consistent, yet ever evolving beers for today’s craft market,” says Marshall Ligare, PhD. Research Scientist at John I. Haas, a leading supplier of hops, hop products and brewing innovations. “We work to ensure brewers can create something different with every new beer, as well as something that helps create an experience as well as a feeling.”

In both brewing and extraction, the art comes in the subjective experience of the craftsman and his or her ability to curate the infinite possibilities inherent in each process. However, both are a science in their requirement of establishing production methodologies that guarantee a consistent, reliable product experience every time to win customer loyalty (and regulatory compliance). In the same way hops determine recipes for beer flavors, the cannabis plant determines extraction recipes, especially considering the role that terpenoids play in the quality, flavor and effects of the end product.

The development of new and appealing cannabis products is beginning to mimic the vast variety of craft beers now found all over the world. In the same way beer connoisseurs seek out the perfect stout, lager or IPA, discriminating cannabis consumers now search for that gem of a single-origin, specialty-strain vaporizer oil or irresistible dab extract.

“I see an exciting new day for quality-focused, craft extraction that tells a story, not only of where the cannabis plant might have been grown and how, but also the care that was taken in the processing of that strain into smokable or edible oil,” says John Lynch, Founder of TradeCraft. “Imagine the impact in the marketplace when product-makers figure out how to do seasonal one-offs where engaged connoisseurs are willing to pay a premium for the art behind limited releases.”

In the same way hops determine recipes for beer flavors, the cannabis plant determines extraction recipes

In either process, you’re essentially creating art with science. Each process works with different strains. Each is concerned with chemical and flavor profiles. Each has its own challenges. In both worlds, quality depends upon consistency. You’re creating art, but you need to replicate that art over and over – which can only occur with strict control of the process. Brewmasters seek control of things like yeast quantity and health, oxygen input, wort nutritional status and temperature, among other things. In their pursuit, extraction technicians seek to control temperature, pressure and flow rate–as well as all the ways these variables interact with each other. What enables this control in both efforts is the equipment used to achieve results.

“A modern brewhouse is very much like a scientific laboratory,” Ligare says. “Brewers treat their setup with the same care and attention a scientist gives to their lab equipment, and are equally concerned with precision, cleanliness and the purity of the result. With each new beer, they want to develop a process that can be controlled and replicated.”

The key to creating a precise process is to use instrument-grade extraction machinery that performs to specifications – and allows you to repeat the process again and again. The value of using high-quality instrumentation to manage and monitor either the brewing or extraction process cannot be overstated. Although it seems counterintuitive, this is where the “craft” comes into play for both brewing and cannabis extraction. Precise instrumentation is what allows the brewer or extraction “artist” to manipulate and monitor the conditions required to meet recipe standards. Along with the quality of the ingredients (hops, cannabis, hemp, etc.), the quality of the equipment utilized to create the product is one critical element impacting the end result. “Imagine the impact in the marketplace when product-makers figure out how to do seasonal one-offs where engaged connoisseurs are willing to pay a premium for the art behind limited releases.”

In cannabis extraction, a second crucial decision is determining which solvent is the best solution for the recipe you’re using and the end result you’re hoping to achieve. This decision is a part of the “craft” of extraction, and determined according to a combination of criteria. There’s no question that each solvent has a business case it serves best, and there is ongoing debate about which approach is best. But overwhelmingly, the solvent that best serves the most business needs is CO₂ due to its inherent versatility and ability to have its density tuned to target specific compounds.

“Control is what makes or breaks any craft product,” says Karen Devereux, Vice President of Northeast Kingdom Hemp. “We’re based in Vermont and love how Vermont is known for its quality craft beer, cheese and maple syrup. We wanted to bring that craft approach to hemp extraction, and everyone knows that any craft endeavor is focused on the details and getting them right again and again. You can’t do that without controlling every aspect of the process.”

Greater control of the process can also open up worlds of discovery. The inherent “tunability” of CO₂ enables the extraction technician to target specific compounds, enhancing the potential for experimentation and even whimsy. This can lead to entirely new products much in the way a brewer can control his process to create new, interesting beers.

American portrait photographer Richard Avedon famously declared that art is “about control,” describing the artistic process as “the encounter between control and the uncontrollable.” The same can be said for beer making and cannabis extraction. The more precisely you can control variables, the more options you’ll have for yourself and your customers. The more choices you’ll have with regard to different recipes and products. And the more loyalty you’ll ultimately generate among fans of your products.

Facility Considerations for Cultivation & Manufacturing: A Case Study

By David Vaillencourt

1 Comment

The cannabis industry is growing and evolving at an unprecedented pace and regulators, consumers and businesses continually struggle to keep up.

Cannabis businesses: How do you maintain an edge on the market, avoid costly mistakes?

Case Study: Costly Facility Build Out Oversights

David Vaillencourt will be joining a panel discussion, Integrated Lifecycle of Designing a Cultivation Operation, on December 22 during the Cannabis Quality Virtual Conference. Click here to register. A vertically integrated multi-state operator wants to produce edibles. The state requires adherence to food safety practices (side note – even if the state did not, adherence to food safety practices should be considered as a major facility and operational requirement). They are already successfully producing flower, tinctures and other oil derivatives. Their architect and MEP firm works with them to design a commercial kitchen for the production of safe edibles. The layout is confirmed, the equipment is specified – everything from storage racks, an oven and exhaust hoods, to food-grade tables. The concrete is poured and walls are constructed. The local health authority comes in to inspect the construction progress, who happens to have a background in industrial food-grade facilities (think General Mills). They remind the company that they must have three-compartment sinks with hot running water for effective cleaning and sanitation, known as clean-out-of-place (COP). The result? Partial demolition of the floor to run pipeline, and a retrofit to make room for the larger sinks, including redoing electrical work and a contentious team debate about the size of the existing equipment that was designed to fit ‘just right.’

Unfortunately, this is just one more common story our team recently witnessed. In this article, I outline a few recommendations and a process (Quality by Design) that could have reduced this and many other issues. For some, following the process may just be the difference between being profitable or going out of business in 2021.

The benefits of Quality by Design are tangible and measurable:

Reduce mistakes that lead to costly re-work
Mitigate inefficient operational flow
Reduce the risk of cross-contamination and product mix-ups. It happens all the time without carefully laid out processes.
Eliminate bottlenecks in your production process
Mitigate the risk of a major recall.

The solution is in the process

Regardless of whether you fall in the category of a food producer, manufacturer of infused products (MIP), food producers, re-packager or even a cultivator, consider the following and ask these questions as a team.

People

Food processing and sanitation — By standardizing and documenting safety procedures, manufacturers mitigate the risk of cannabis-specific concerns

For every process, who is performing it? This may be a single individual or the role of specific people as defined in a job description.

Does the individual(s) performing the process have sufficient education and training? Do you have a diverse team that can provide different perspectives? World class operations are not developed in a vacuum, but rather with a team. Encourage healthy discourse and dialogue.

Process

Is the process defined? Perhaps in a standard operating procedure (SOP) or work instruction (WI). This is not the general guidance an equipment vendor provided you with, this is your process.

How well do you know your process? Does your SOP or WI specify (with numbers) how long to run the piece of equipment, the specification of the raw materials used (or not used) during the process, and what defines a successful output?

Do you have a system in place for when things deviate from the process? Processes are not foolproof. Do not get hung up on deviations from the process, but don’t turn a blind eye to them. Record and monitor them. In time, they will show you clear opportunities for improvement, preventing major catastrophes.

Materials

What are the raw materials being used? Where are they coming from (who is your supplier and how did you qualify them)?

Start with the raw materials that create your product or touch your product at all stages of the process. We have seen many cases where cannabis oils fail for heavy metals, specifically lead. Extractors are quick to blame the cultivator and their nutrients, as cannabis is a very effective phytoremediator (it uptakes heavy metals and toxins from soil substrate). The more likely culprit – your glassware! Storing cannabis oil, both work in process or final product in glass jars, while preferred over plastic, requires due diligence on the provider of your glassware. If they change the factory in which it is produced, will you be notified? Stipulate this in your contract. Don’t find yourself in the next cannabis lead recall that gets the attention of the FDA.

Savings is gained through simple control of your raw materials. Variability in your raw material going into the extractor is inevitable, but the more you can do to standardize the quality of your inputs, the less work re-formulating needs to be done downstream. Eliminate the constant need to troubleshoot why yields are lower than expected, or worst case, having to rerun or throw an entire batch out because it was “hot” (either too much THC in the hemp/CBD space or pesticides/heavy metals). These all add up to significant downstream bottlenecks – underutilized equipment, inefficient staff (increase in labor cost) all because of a lack of upstream controls. Use your current process as a starting point, but implement a quality system to drive improvement in operational efficiency and watch your top line grow while your bottom-line decreases.

Consistency in quality standards requires meticulous SOPs

Have you tested and confirmed the quality of your raw material? This isn’t just does it have THC and is it cannabis, but is it a certain particle size, moisture level, etc.? Again, define the quality of your raw materials (specifications) and test for it.

Remember – ranges are your friend. It is much better to say 9-13% moisture than “about 10%”. For your most diligent extractor, 11% will be unacceptable, but for a guy that just wants to get the job done, 13% just may do!

Test your final product AFTER the process. Again, how does it stack up against your specifications? You may need to have multiple specifications based on different types of raw material. Perhaps one strain with a certain range of cannabinoids and terpenes can be expected for production.

Review the data and trend it. Are you getting lower yields than normal? This may be due to an issue with the equipment, maybe a blockage has formed somewhere, a valve is loose, and simple preventive maintenance will get you back up and running. Or, it could be that the raw biomass quality has changed. Either way, having that data available for review and analysis will allow you to identify the root cause and prevent a surprise failure of your equipment. Murphy’s law applies to the cannabis industry too.

You are able to predict and prevent most failures before they occur
You increase the longevity of your equipment
You are able to predict with a level of confidence – imagine estimating how much product you will product next month and hitting that target – every time!
Business risks are significantly mitigated – a process that spews out metal, concentrates heavy metals or does not kill microbes that were in the raw material is an expensive mistake.
Your employees don’t feel like they are running around with their hair on fire all the time. It’s expensive to train new employees. Reduce your turnover with a less stressed-out team.

Takeaways

Maintaining a competitive edge in the cannabis industry is not easy, but it can be made easier with the right team, tools and data. Our recommendations boil down to a few simple steps:

Make sure you have a chemical or mechanical engineer to understand, optimize and standardize your process (you should have one of these on staff permanently!)
Implement a testing program for all raw materials
1. Test your raw materials – cannabis flower, solvents, additives, etc. before using. Work with your team to understand what you should and should not test for, and the frequency for doing so. Some materials/vendors are likely more consistent or reliable than others. Test the less reliable ones more frequently (or even every time!)
Test your final product after you extract it – Just because your local regulatory body does not require a certain test, it does not mean you should not look for it. Anything that you specified wanting the product to achieve needs to be tested at an established frequency (and this does not necessarily need to be every batch).
Repeat, and record all of your extraction parameters.
Review, approve and set a system in place for monitoring any changes.

Congratulations, you have just gone through the process of validating your operation. You may now begin to realize the benefits of validating your operation, from your personnel to your equipment and processes.

Could CBD Standards Become Global?

By Marguerite Arnold

No Comments

Here is the good news: There are beginning to be regional- and country-specific guidelines on at least one widely grown cannabis crop internationally. This includes a range of regs on the medical side (GMPs) but they are also expanding for the “other” cannabis crop too. Namely, hemp.

Now, here is the bad news: The regulation that is developing in different regions is frustratingly not uniform, and can still differ greatly in critical areas. Most notably, for some reason, while the U.S. Farm Bill of 2018 created a new national standard for the amount of THC that could be contained in American hemp crops (0.3%), the same conversation in Europe during the same period of time led to a decision to set the level of allowable THC in hemp plants and products at a slightly lower one: 0.2%. As a further confusing muddle, Switzerland has set its THC limits at 0.1% (Switzerland is not in the European Union), and other countries across the region have also attempted to limit the THC in industrial hemp production to no more than this level, no matter what regulators rule at the EU level.

Just some of the many CBD products on the market today.

Beyond a lack of scientific reasoning obvious in the same, by definition, this creates a natural trade barrier between hemispheres. If U.S. farmers are looking for export opportunities to Europe (for example) not to mention other states, they have to worry about both local as well as destination standards – which on the surface at least, are currently incompatible.

It is also creating some frustrating issues for anyone who is in the market for hemp as either a buyer or seller.

Other Issues In The Mix
Markets are driven by many factors – including regulations but also cost and of course consumer demand for a product within a certain price range. Certainly, the CBD industry if not the recreational THC one right behind it (even in Europe now) desperately wants to attract those who are known euphemistically as “daily consumers.”

This means that both the price point and consumer opportunities must hit a mainstream distribution norm. While the recreational market will continue to be distorted by delayed, but inevitable discussions about reform across Europe, the medical market is beginning to set some groundwork that is also bleeding into the entire discussion. Namely, that extracts will play a large role here.

What does this wrinkle mean in a world where the agricultural cultivation standards are different?

Biomass And Extracts Are Gaining In Importance
For those in the strictly “flower” game, the market at least in the U.S., will remain a place where pretty flower crops will gain premium prices as long as they meet local spec.

However, this is a limited proposition, even now – especially in the CBD business. The edibles market, for one, has created a huge potential for vast quantities of industrially produced, outdoor grown hemp, bound for extraction and downstream, a vast variety of end products across a wide spectrum of niches – from wellness to purely cosmetic. So is the burgeoning medical market in Europe.

This means two things. The first is that consumer-facing products with any amount of cannabinoid (take your pick) can be produced to order, no matter the cannabinoid concentrations of the original plant. The second, by definition, means that biomass bound for extraction, particularly export, will gain an increasingly larger share of the wholesale market.

Does it really matter, in other words, to a European extractor, that the source product is of higher THC concentrate than is allowed for B2C sale in Europe? No. Indeed, all it means is that they have to buy lower amounts of biomass. The rest is merely a mechanical problem.

Playing The Regulatory Game
For an increasingly competitive hemp market in the United States, in other words, foreign exports are absolutely an intriguing option for revenue right now, and will continue to be as long as price competitiveness and overall quality issues remain high. Furthermore, there will be almost no pressure to regulate the market globally to the same standards, particularly if CBD itself is descheduled in December by the WHO.

In other words, the regulatory disconnect between the U.S. and Europe right now, and certainly for certain kinds of unfinished bulk product, could therefore open a new niche in the market that is unlikely to be “fixed” anytime soon.

Orange Photonics Introduces Terpenes+ Module in Portable Analyzer

By Aaron G. Biros

No Comments

Last week at the National Cannabis Industry Association’s (NCIA) Cannabis Business Summit, Orange Photonics unveiled their newest product added to their suite of testing instruments for quality assurance in the field. The Terpenes+ Module for the LightLab Cannabis Analyzer, which semi-quantitatively measures terpenes, Cannabichromene (CBC) and degraded THC, adds three new chemical analyses to the six cannabinoids it already reports.

CBC, a cannabinoid typically seen in hemp and CBD-rich plants, has been linked to some potentially impactful medical applications, much like the findings regarding the benefits of CBD. The module that tests for it, along with terpenes and degraded THC, can be added to the LightLab without any changes to hardware or sample preparation.

According to Dylan Wilks, chief technology officer of Orange Photonics, this could be a particularly useful tool for distillate producers looking for extra quality controls. Cannabis distillates are some of the most prized cannabis products around, but the heat used to create them can also create undesirable compounds,” says Wilks. “Distillate producers can see potency drop more than 25% if their process isn’t optimized”. With this new Terpenes+ Module, a distillate producer could quantify degraded THC content and get an accurate reading for their QC/QA department.

We spoke with Stephanie McArdle, president of Orange Photonics, to learn more about their instruments designed for quality assurance for growers and extractors alike.

According to McArdle, this could help cultivators and processors understand and value their product when terpene-rich products are the end goal. “Rather than try to duplicate the laboratory analysis, which would require expensive equipment and difficult sample preparation, we took a different approach. We report all terpenes as a single total terpene number,” says McArdle. “The analyzer only looks for monoterpenes (some common monoterpenes are myrcene, limonene and alpha-pinene), and not sesquiterpenes (the other major group of cannabis terpenes, such as Beta- Caryophyllene and Humulene) so the analysis is semi-quantitative. What we do is measure the monoterpenes and make an assumption that the sesquiterpenes are similar to an average cannabis plant to calculate a total terpene content.” She says because roughly 80% of terpenes found in cannabis are monoterpenes, this should produce accurate results, though some exotic strains may not result in accurate terpene content using this method.

As growers look to make their product unique in a highly competitive market, many are looking at terpenes as a source of differentiation. There are a variety of areas where growers can target higher terpene production, McArdle says. “During production, a grower may want to select plants for growing based on terpene content, or adjust nutrient levels, lighting, etc. to maximize terpenes,” says McArdle. “During the curing process, adjusting the environmental conditions to maximize terpene content is highly desirable.” Terpenes are also beginning to get recognized for their potential medical and therapeutic values as well, notably as an essential piece in the Entourage Effect. “Ultimately, it comes down to economics – terpene rich products have a higher market value,” says McArdle. “If you’re the grower, you want to prove that your product is superior. If you’re the buyer, you want to ensure the product you buy is high quality before processing it into other products. In both cases, knowing the terpene content is critical to ensuring you’re maximizing profits.”

Orange Photonics’ LightLab operates very similarly to instruments you might find in a cannabis laboratory. Many cannabis testing labs use High Performance Liquid Chromatography (HPLC) to analyze hemp or cannabis samples. “The primary difference between LightLab and an HPLC is that we operate at lower pressures and rely on spectroscopy more heavily than a typical HPLC analysis does,” says McArdle. “Like an HPLC, LightLab pushes an extracted cannabis sample through a column. The column separates the cannabinoids in the sample by slowing down cannabinoids by different amounts based on their affinity to the column.” McArdle says this is what allows each cannabinoid to exit the column at a different time. “For example, CBD may exit the column first, then D9THC and so on,” says McArdle. “Once the column separates the cannabinoids, they are quantified using optical spectroscopy- basically we are using light to do the final quantification.”

CannaGrow Expo Heads to Palm Springs

By Aaron G. Biros

No Comments

We’ve covered the CannaGrow Expo previously, but this time around we catch up with Joseph De Palma, founder of CannaGrow, to talk about the genesis of his conference and what makes the event so special. This year’s CannaGrow Expo heads to Palm Springs, California, a new location for the event, on May 19^thand 20^th.

We’ve watched De Palma’s conference grow over the years, moving around the country and becoming the tight-knit community we know it as today. The meat and potatoes of the show are definitely the educational sessions, panel discussions, roundtables and the expo hall. But covering it year after year we’ve noticed a real sense of community develop, one where genuine idea sharing, collaboration and inclusivity are preached. There are no dumb questions at the CannaGrow Expo.

According to Joseph De Palma, CannaGrow started in 2014, when the original event was held in Denver. “From the beginning, we wanted to create an event specifically for growers, where the focus was always on education and ‘becoming a better grower’,” says De Palma. “We had experienced the existing events in the marketplace, and almost all fit into two categories at the time, festival, or generic tradeshow. Those were fine for their purpose, but they didn’t foster an environment of education, and that’s what we believed was most important to the emerging cannabis industry.” Back in 2014, their show only had 10 sessions and 30 exhibitors. “Passionate growers from around the country had 2 days of grow-focused sharing and learning, and you could see the energy and excitement,” De Palma says. “Discussions would dive deep, people made new friends, and it really elevated the conversation around cultivation.”

Since the show’s debut, it’s grown substantially. The 7^th CannaGrow Expo is fast approaching, and this upcoming conference has four separate tracks and roughly 100 exhibitors. But it still keeps its sense of community, one where you don’t feel crowded, where everyone has time to chat and network, without the overwhelming feeling that can come with larger trade shows. “That inclusivity and open dialog is built in,” says De Palma. “If you go to an event that’s tradeshow dominant, most people are there to walk, shop, and leave. At CannaGrow, growers and extractors come together with a plan for the weekend, remaining in a constant state of engagement with others at the show.”

This year’s show has some exciting additions to look out for. The agenda covers a wide range of topics, including everything from an introduction to growing with living soil to a discussion of cyber security. The Extraction Summit, new to this year’s event and held on Day 2, is their response to the massive rise in popularity and demand of extracts.

Eric Schlissel, cybersecurity specialist, president and chief executive officer of GeekTek, is giving a talk focused on IT infrastructure. “My presentation will center around the actions cannabis businesses need to take right now to repel cybercrime and potential federal seizure,” says Schlissel. “As cannabis operators build their businesses and develop their security strategies, they often focus exclusively on the physical portion of their business – the merchandise and the cash in particular – and overlook the importance of designing and fortifying a secure IT infrastructure. I will discuss the importance of a holistic security strategy that embraces both and how you can both create one and prepare it for expansion into other states or even globally from the very start.” Schlissel’s discussion is one example of just how all-encompassing CannaGrow intends to be.

De Palma and his team leave few stones unturned as the show truly delivers vital information for cannabis cultivators in every area. Some things we are looking forward to? Seeing old friends and learning everything under the sun about cannabis science, growing and extraction. “People get to know each other, and with everyone sharing a core passion for cultivation and extraction, lifelong friendships are made,” says De Palma.

Quality Assurance In The Field: Instruments For Growers & Processors

By Aaron G. Biros

As the cannabis marketplace evolves, so does the technology. Cultivators are scaling up their production and commercial-scale operations are focusing more on quality. That greater attention to detail is leading growers, extractors and infused product manufacturers to use analytical chemistry as a quality control tool.

Previously, using analytical instrumentation, like mass spectrometry (MS) or gas chromatography (GC), required experience in the laboratory or with chromatography, a degree in chemistry or a deep understanding of analytical chemistry. This leaves the testing component to those that are competent enough and scientifically capable to use these complex instruments, like laboratory personnel, and that is still the case. As recent as less than two years ago, we began seeing instrument manufacturers making marketing claims that their instrument requires no experience in chromatography.

Instrument manufacturers are now competing in a new market: the instrument designed for quality assurance in the field. These instruments are more compact, lighter and easier to use than their counterparts in the lab. While they are no replacement for an accredited laboratory, manufacturers promise these instruments can give growers an accurate estimate for cannabinoid percentages. Let’s take a look at a few of these instruments designed and marketed for quality assurance in the field, specifically for cannabis producers.

Ellutia GC 200 Series

Ellutia is an instrument manufacturer from the UK. They design and produce a range of gas chromatographs, GC accessories, software and consumables, most of which are designed for use in a laboratory. Andrew James, marketing director at Ellutia, says their instrument targeting this segment was originally designed for educational purposes. “The GC is compact in size and lightweight in stature with a full range of detectors,” says James. “This means not only is it portable and easy to access but also easy to use, which is why it was initially intended for the education market.”

That original design for use in teaching, James says, is why cannabis producers might find it so user-friendly. “It offers equivalent performance to other GC’s meaning we can easily replace other GC’s performing the same analysis, but our customers can benefit from the lower space requirement, reduced energy bills, service costs and initial capital outlay,” says James. “This ensures the lowest possible cost of ownership, decreasing the cost per analysis and increasing profits on every sample analyzed.”

Shamanics, a cannabis oil extraction company based in Amsterdam, uses Ellutia’s 200 series for quality assurance in their products. According to Bart Roelfsema, co-founder of Shamanics, they have experienced a range of improvements in monitoring quality since they started using the 200 series. “It is very liberating to actually see what you are doing,” says Roelfsema. “If you are a grower, a manufacturer or a seller, it is always reassuring to see what you have and prove or improve on your quality.” Although testing isn’t commonplace in the Netherlands quite yet, the consumer demand is rising for tested products. “We also conduct terpene analysis and cannabinoid acid analysis,” says Roelfsema. “This is a very important aspect of the GC as now it is possible to methylate the sample and test for acids; and the 200 Series is very accurate, which is a huge benefit.” Roelfsema says being able to judge quality product and then relay that information to retail is helping them grow their business and stay ahead of the curve.

908 Devices G908 GC-HPMS

908 Devices, headquartered in Boston, is making a big splash in this new market with their modular G908 GC-HPMS. The company says they are “democratizing chemical analysis by way of mass spectrometry,” with their G908 device. That is a bold claim, but rather appropriate, given that MS used to be reserved strictly for the lab environment. According to Graham Shelver, Ph.D., commercial leader for Applied Markets at 908 Devices Inc., their company is making GC-HPMS readily available to users wanting to test cannabis products, who do not need to be trained analytical chemists.

Shelver says they have made the hardware modular, letting the user service the device themselves. This, accompanied by simplified software, means you don’t need a Ph.D. to use it. “The “analyzer in a box” design philosophy behind the G908 GC-HPMS and the accompanying JetStream software has been to make using the entire system as straightforward as possible so that routine tasks such as mass axis calibration are reduced to simple single actions and sample injection to results reporting becomes a single button software operation,” says Shelver.

He also says while it is designed for use in the field, laboratories also use it to meet higher-than-usual demand. Both RM3 Labs in Colorado, and ProVerde in Massachusetts, use G908. “RM3’s main goal with the G908 is increased throughput and ProVerde has found it useful in adding an orthogonal and very rapid technique (GC-HPMS) to their suite of cannabis testing instruments,” says Shelver.

Orange Photonics LightLab Cannabis Analyzer

Dylan Wilks, a third generation spectroscopist, launched Orange Photonics with his team to produce analytical tools that are easy to use and can make data accessible where it has been historically absent, such as onsite testing within the cannabis space. According to Stephanie McArdle, president of Orange Photonics, the LightLab Cannabis Analyzer is based on the same principles as HPLC technology, combining liquid chromatography with spectroscopy. Unlike an HPLC however, LightLab is rugged, portable and they claim you do not need to be a chemist to use it.

“LightLab was developed to deliver accurate repeatable results for six primary cannabinoids, D9THC, THC-A, CBD, CBD-A, CBG-A and CBN,” says McArdle. “The sample prep is straightforward: Prepare a homogenous, representative sample, place a measured portion in the provided vial, introduce extraction solvent, input the sample into LightLab and eight minutes later you will have your potency information.” She says their goal is to ensure producers can get lab-grade results.

The hard plastic case is a unique feature of this instrument

McArdle also says the device is designed to test a wide range of samples, allowing growers, processors and infused product manufacturers to use it for quality assurance. “Extracts manufacturers use LightLab to limit loss- they accurately value trim purchases on the spot, they test throughout their extraction process including tests on spent material (raffinate) and of course the final product,” says McArdle. “Edibles manufacturers test the potency of their raw ingredients and check batch dosing. Cultivators use LightLab for strain selection, maturation monitoring, harvesting at peak and tinkering.”

Orange Photonics’ instrument also connects to devices via Wi-Fi and Bluetooth. McArdle says cannabis companies throughout the supply chain use it. “We aren’t trying to replace lab testing, but anyone making a cannabis product is shooting in the dark if they don’t have access to real time data about potency,” says McArdle.
