Last week, just before MJBizCon, PerkinElmer announced a collaboration with Emerald Scientific, allowing Emerald Scientific customers access to PerkinElmer’s portfolio of cannabis and hemp testing products and services. PerkinElmer is a leading instrument manufacturer and analytical method developer. Emerald Scientific is a distributor for scientific lab testing equipment and instrumentation.

Emerald Scientific now offers their customers PerkinElmer products, like their QSight® 420 Triple Quad system LC/MS, the Titan MPS™ Microwave Sample Preparation System, the Clarus® SQ 8 Gas Chromatograph/Mass Spectrometer (GC/MS) and the Flexar™ High-Performance Liquid Chromatography (HPLC) system. This partnership also allows Emerald Scientific customers to utilize the PerkinElmer analytical methods and standard operating procedures (SOPs) for cannabis and hemp testing. That includes SOPs for things like sample preparation, acquisition methods and consumable use. They’ll also be able to shop for lab products like PerkinElmer’s chromatography columns, vials and sample prep products.

According to Greg Sears, vice president and general manager, Food and Organic Mass Spectrometry at PerkinElmer, the cannabis testing market is exploding and this will help labs get their equipment and necessities all in the same place. “With the cannabis and hemp markets continuing to grow rapidly and regulations strengthening, labs increasingly need streamlined access to best-in-class, user-friendly testing solutions geared toward the unique requirements of the industry,” says Sears. ““This collaboration with Emerald Scientific brings together leading cannabis analysis offerings in one place to help labs start up and expand more efficiently.  In addition, we can build on the work we have done with Emerald around testing standardization which is important for the science of the industry.”

Kirsten Blake, Vice President of Emerald Scientific, says they are really excited about the partnership. “As regulations become more challenging, laboratory competition intensifies, and the science of the industry receives increasing focus, it is essential to align with organizations dedicated to improving both the quality and throughput of analytics,” says Blake. “After working with PerkinElmer to inform, educate, and advance the cannabis science industry around best practices, we see them as the industry leader for providing analytical instrumentation, methods and SOP’s. By adding their complementary solutions to our existing portfolio, we can now deliver complete packaged analytical solutions to the cannabis and hemp industries.”

PerkinElmer Awarded Five Emerald Test Badges

According to a press release published today, Emerald Scientific awarded PerkinElmer five badges for The Emerald Test, a bi-annual Inter-Laboratory Comparison and Proficiency Test (ILC/PT) program. Awarding the badges for Perkin Elmer’s instruments and testing methods affirms their ability to accurately detect pesticides, heavy metals, residual solvents, terpenes and potency in cannabis.

According to Greg Sears, vice president and general manager of Food, Chromatography & Mass Spectrometry, Discovery & Analytical Solutions at PerkinElmer, they are the only instrument manufacturer to receive all five accolades. “To date, PerkinElmer is the only solutions provider to successfully complete these five Emerald Scientific proficiency tests,” says Sears. “The badges underscore our instruments’ ability to help cannabis labs meet the highest standards available in the industry and effectively address their biggest pain point: Navigating diverse regulations without compromising turnaround time.”

The instruments used were PerkinElmer’s QSight 220 and 420 Triple Quad systems, which are originally designed for accurate and fast detection/identification of “pesticides, mycotoxins and emerging contaminants in complex food, cannabis and environmental samples,” reads the press release. They also used their ICP-MS, GC/MS and HPLC systems for the badges.

PerkinElmer says they developed a single LC/MS/MS method using their QSight Triple Quad systems, which helps labs test for pesticides and mycotoxins under strict regulations in states like California and Oregon. They performed studies that also confirm their instruments can help meet Canada’s testing requirements, which set action limits nearly 10 times lower than California, according to the press release.

‘Instant’ Cannabis Potency Testing: Different Approaches from Different Manufacturers

This is the first piece of a regular column that CIJ has been so kind to allow me to write for their publication. Some readers might recognize my name from The Practical Chemist column in this publication. Since the inception of that column, I’ve finally taken the plunge into the cannabis industry as chief technical officer of Emerald Scientific. Unlike The Practical Chemist, I will not spend the entire first article introducing the column. The concept is simple: while I find the textbook-esque content of The Practical Chemist scintillating, I have a feeling that the content is a little too heavy to spring on someone who is looking for engaging articles over their precious coffee break. Instead, The Nerd Perspective will consist of less-technical writing focusing on my experience and insights for the cannabis industry as a whole. But don’t worry – I’m sure I will not be able to refrain from technical jargon altogether.

To kick off the column, I want to talk about instrumentation for ‘instant’ cannabis potency testing. At this point, it’s common knowledge in the cannabis analytics industry that the most accurate way to test cannabis potency is through extraction then analysis by HPLC-UV. I agree wholeheartedly with that sentiment, but HPLC analyses have one drawback: they can be either inexpensive or fast – not both. There are some instruments entering the market now that– while not as directly quantitative as HPLC-UV – promise to solve the inexpensive/fast conundrum. During my most recent trip to California, I was able to spend some quality time with two well-known instrument manufacturers: SRI Instruments and PerkinElmer, both of whom manufacture instruments that perform fast, inexpensive cannabis potency analyses. From my previous home at the heights of The Ivory Tower of Chromatography: Home of the Application Chemists, SRI and PE couldn’t be more different. But as seen through the eyes of a company who deals with a wide range of customers and analytical needs, it turns out that SRI and PE are much the same – not only in their open and honest support of the cannabis industry, but also in terms of their love of all things technical.

My first stop was SRI Instruments. They are a relatively small company located in an unassuming building in Torrance, CA. Only a few people work in that location, and I spent my time with Hugh Goldsmith (chief executive officer) and Greg Benedict (tech service guru). I have worked with these guys for a few years now, and since the beginning, I have lovingly referred to them as the MacGyvers of chromatography. Anyone familiar with SRI GCs knows that what they lack in aesthetics, they make up for in practicality – these instruments truly reflect Hugh and Greg’s character (that’s meant as a compliment).

SRI specializes in relatively inexpensive portable and semi-portable instruments that are easy to set up, easy to operate, and most importantly – engineered for a purpose. It’s actually really hard to manufacture an instrument that meets all three of these criteria, and the folks at SRI accomplish this with their passionate and unique approach to problem solving. What I love about these guys is that for them, nothing is impossible. Here’s an example: the price of the portable GC-FID instruments SRI builds is inflated because the instruments require separate – and pricey – hydrogen generators. That’s a big problem – hydrogen generators are all pretty much the same, and none of them are cheap. This didn’t faze SRI: they just decided to design their own super small on-board hydrogen generator capable of supplying hydrogen to a simple GC macgyversystem for six hours with just 20mL of distilled water from the grocery store! I’m not kidding – I saw it in action on their new Model 420 GC (more on that in some future pieces). Was the final product pretty? Not in the least. Did it work? Absolutely. This kind of MacGyver-esque problem solving can only be done successfully with a deep understanding of the core principles behind the problem. What’s more, in order to engineer instruments like these, SRI has to have mastery over the core principles of not only chromatographic separation, but also of software development, electrical engineering, and mechanical engineering – just to name a few. These quirky, unassuming guys are smart. SRI is a company that’s been unapologetically true to themselves for decades; they’ll never be a contender for beauty queen, but they get the job done.

On the surface, PerkinElmer (PE) contrasts with SRI in almost every way possible. With revenue measured in billions of dollars and employees numbering in the thousands, PE is a behemoth that plays not only in the analytical chemistry industry but also in clinical diagnostics and other large industries. Where SRI instruments have a characteristic look of familiar homeliness, PE instruments are sleek and sexy. However, PerkinElmer and SRI are more alike than it would seem; just like the no-frills SRI, the hyper-technical PE instruments are engineered for a purpose by teams of very smart, passionate people.

DoogieWith its modest price tag and manual sample introduction, the SRI Model 420 is engineered for lower throughput users to be a fast, simple, and inexpensive approach to semi-quantitative process control. The purpose of the instruments manufactured by PE is to produce the highest-quality quantitative results as quickly as possible for high-throughput labs. PE instruments are built using the best technology available in order to eke out every last ounce of quantitative accuracy and throughput possible. Fancy technology is rarely inexpensive, and neither is rigorous product development that can last years in some cases. In a way, PE is Doogie Howser to SRI’s MacGyver. Like MacGyver, Doogie is super smart, and his setting is a sterile hospital rather than a warzone.

I had a wonderful conversation with Tim Ruppel, PE’s headspace-GC specialist, on the sample introduction technology incorporated into the TurboMatrix Headspace Sampler, where I also learned that the basic technology for all PerkinElmer headspace-GC instruments was designed by the men who wrote The Book on headspace gas chromatography: Bruno Kolb and Leslie Ettre**. Later, I was able to get a much-needed lesson on FT-IR and the Spectrum Two IR Spectrometer from Brian Smith, PE’s spectroscopy expert, who actually wrote the book on quantitative spectroscopy***. Tim and Brian’s excitement over their technology mirrored that of Hugh and Greg. It turns out that SRI and PerkinElmer are more alike than I thought.

These two instrument manufacturers have addressed the fast/inexpensive conundrum of cannabis potency testing in two different ways: SRI’s instrument is extremely inexpensive, easy to operate, and will provide semi-quantitative values for THC, CBD, and CBN in just a few minutes; PE’s instrument is more expensive up front, but provides quantitative (though not directly quantitative) values for all of the major cannabinoids almost instantly, and requires almost no maintenance or consumables. These two instruments were designed for specific uses: one for inexpensive, easy use, and the other for more comprehensive results with a higher initial investment. The question consumers have to ask themselves is “Who do I need to solve my problem?” For some, the answer will be MacGyver, and for others, Doogie Howser will provide the solution – after all, both are heroes.
