Quality Assurance In The Field: Instruments For Growers & Processors

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.

Greenhouse Ventures, Thomas Jefferson University’s Lambert Center Launch Education Series

Greenhouse Ventures, a startup accelerator for ancillary businesses in the cannabis space, announced today the launch of a series of educational events throughout Pennsylvania, partnering with The Lambert Center for the Study of Medicinal Cannabis and Hemp at Thomas Jefferson University. According to the press release, the series of talks will be focused on Pennsylvania’s legislation regarding medical cannabis.

“The PA Medicinal Cannabis Education Tour seeks to rectify the current lack of education on medicinal cannabis by providing current, reliable information on medicinal marijuana and its uses,” reads the press release. The events come at an opportune time: Pennsylvania recently announced qualifying permit applications for growers and dispensaries. As the state moves forward with their plan to fully implement a medical cannabis program by 2018, those looking to learn more about the regulations can attend these talks throughout the state.

The PA Medicinal Cannabis Education Tour will make stops in six cities, one for each of the regions set by the Department of Health: Tuesday, July 25th in Philadelphia; Wednesday, July 26th in Allentown; Tuesday, August 1st in Pittsburgh; Wednesday, August 2nd in Erie; Tuesday, September 26th in Harrisburg and Wednesday, September 27th in State College. The educational content is developed by the Lambert Center at Thomas Jefferson, the only such program dedicated to cannabinoid therapy. “These programs will educate healthcare professionals on the basic science underlying the pharmacologic and therapeutic options associated with medical cannabis in patient care, clinical insights on the use of medicinal cannabis, and provide information on legislative measures of Pennsylvania state law on the use, recommendation and dispensing of medical marijuana for medical conditions,” reads the press release.

Last year, The Lambert Center hosted an accredited CME course as part of Greenhouse Ventures’ industry conference, Innovation in the Cannabis Industry: Future Outlook. “The Lambert Center for the Study of Medicinal Cannabis and Hemp at Thomas Jefferson University is proud to support and participate in the PA Medicinal Cannabis Education Tour,” says Charles V. Pollack, Jr., MD, director of the Lambert Center. “The Lambert Center is the only comprehensive academic resource for education, research, and practice for the therapeutic use of cannabinoids to be based in a US health sciences university. We view the PA Tour as an essential education piece to prepare Pennsylvania doctors and assist in a smooth rollout of Pennsylvania’s Medical Cannabis industry.”

Sara Jane Ward, PhD, is an assistant professor at the Center for Substance Abuse and Research at the Lewis Katz School of Medicine at Temple University and one of the course instructors on the education tour. She says a large part of the event series is to settle old misconceptions about cannabis. “There are a lot of misconceptions and misunderstandings on cannabis as a medicine in the medical community, because historically medical students are not taught about cannabis and the endocannabinoid system,” says Ward. “I’m looking forward to working with Greenhouse Ventures and The Lambert Center for the Study of Medicinal Cannabis and Hemp, to educate healthcare professionals across Pennsylvania on the health benefits of cannabis.”

“A common setback for states that are implementing medical cannabis regulations is the lack of interest and sign ups from doctors and patients,” says Kevin Provost, executive officer of Greenhouse Ventures. “With reputable medical institutions like Thomas Jefferson University providing entry level education on medicinal cannabis and the endocannabinoid system, hopefully healthcare professionals across the state will realize this is real medicine, that can bring significant medical benefits to thousands of patients, and that now is the time for them to learn, before the industry is open in Pennsylvania.”

The first event in the educational series will be in Center City, Philadelphia on Tuesday, July 25th in the Bluemle Life Sciences Building at Thomas Jefferson University.
