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.”

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 19thand 20th.

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 7th 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.

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.
