Yesterday, Shimadzu announced the formation of a partnership with Cure Pharmaceutical Group and CK Sciences to research and develop pharmaceutical cannabis-based products, according to a press release. The three organizations entered a collaborative agreement with the goal of researching and developing products, then moving them through clinical trials using FDA guidelines.
According to the press release, the partnership’s primary goal will be researching and profiling the synergistic effects of the cannabinoids and terpenes, called the “Entourage Effect.”
Shimadzu, a well-know analytical instrument manufacturer, has been making a name for itself in the scientific cannabis space with a number of exciting new ventures. They have worked extensively with cannabis laboratories throughout the country in refining methods and improving analytical chemistry in the space. For example, Shimadzu powers EVIO Labs Florida with over $1.2 million in the latest testing instrumentation.
Tracy Ryan, chief executive officer and founder of CK Sciences, says outfitting their lab for pharmaceutical research was a big priority for starting their venture. “When we met with Shimadzu, and we saw their passion for our mission, we knew we were in incredible hands! When analyzing cannabis everything has to be so precise,” says Ryan. “With Shimadzu’s platforms and team of brilliant scientists supporting our efforts, we have already set ourselves up for success.”
Back in March, Shimadzu launched their Cannabis Analyzer for Potency, a high-performance liquid chromatograph (HPLC) designed specifically for quantitative determination of cannabinoid content. The organizations in the partnership will be using that instrument, in addition to a headspace Gas Chromatograph Mass Spectrometer (GCMS) for terpene profiling. Both Cure and CK will use the instruments to generate data, with the goal to validate cannabis as a viable pharmaceutical treatment, according to the press release.
Bob Clifford, Ph.D., general manager of marketing for Shimadzu, says they are excited to work with the organizations. “The emerging pharmaceutical cannabis market requires dedicated, thoughtful leaders eager to showcase the pharmaceutical benefits of cannabis on a scientific level,” says Clifford. “The Cure/CK Sciences group has continuously demonstrated such a leadership commitment, and we’re excited about the opportunities this agreement provides.”
Steve Stadlmann has an extensive background as an analytical chemist working in laboratories since the early 90’s. He is now a sales specialist at PerkinElmer, an analytical instrument manufacturer that provides instruments for cannabis testing labs, in addition to a host of other industries. With over two decades of experience working in environmental testing labs, food and beverage labs and agricultural testing labs, Stadlmann is extremely familiar with the instruments used in cannabis labs.
In 2014, he started working in the cannabis space with TriQ, Inc., a technology solutions provider for cannabis growers, where he worked in product development on a line of nutrients. In April of 2016, he started working at Juniper Analytics, a cannabis-testing laboratory in Bend, Oregon. As laboratory director there, he created their quality manual, quality assurance plan, SOP’s and all the technical documentation for ORELAP accreditation. He developed new methodologies for cannabis testing industry for residual solvents, terpene profiles and potency analysis. He worked with PerkinElmer on pesticide methodology for the QSight™ Triple Quadrupole LC/MS/MS system and implemented operational procedures and methods for LC-UV, GCMS and LC-MS/MS, including sample prep for cannabis products.
He left Juniper Analytics about two months ago to work with PerkinElmer as a sales specialist. With extensive experience in helping get Juniper’s lab accredited, he is a wealth of knowledge on all things cannabis laboratory accreditation. PerkinElmer will be hosting a free webinar on September 12th that takes a deep dive into all things cannabis lab accreditation. Ahead of the upcoming webinar, Getting Accreditation in the Cannabis Industry, we sit down with Stadlmann to hear his observations on what instruments he recommends for accreditation, and processes and procedures to support that. Take a look at our conversation below to get a glimpse into what this webinar will discuss.
CannabisIndustryJournal: How can cannabis labs prepare for accreditation with selecting instrumentation?
Steve: Finding the appropriate instrumentation for the regulations is crucial. Ensuring the instrumentation not only has the capabilities of analyzing all the required compounds, but also able to achieve appropriate detection limit requirements. In addition, having an instrument manufacturer as a partner, that is willing and able to assist in method development, implementation and continued changes to the testing requirements at the state level (and potentially national level) is key.
Another consideration is robustness of the equipment. The instrumentation must be capable of high throughput for fast turnaround times of results. Unlike the environmental industry, the cannabis industry has consumer products with expiration dates. Clients demand quick turnaround of results to get product to market as quickly as possible and avoid sitting on inventory for any length of time.
To add to the robustness need, sample matrices in the cannabis industry can be quite challenging in relation to analytical instrumentation. Equipment that is able to handle these matrices with minimal downtime for routine service is becoming a requirement to maintain throughput needs of the industry.
CIJ: What are the most crucial procedures and practices for achieving ISO 17025 accreditation?
Steve: Development and documentation of processes and procedures following Good Laboratory Practices and procedures is essential to a successful accreditation process. Great attention must be paid to the quality objectives of the laboratory as well as associated documentation, including tracking of any errors, deviations, updates, complaints, etc.
Data integrity is a key component to any accrediting body and includes implementation and/or development of appropriate methods with support data proving acceptable results. In addition, documentation of all procedures and processes along with tracking of all steps in the process during routine laboratory work should be a priority. The ability to show a complete, documented trail of all procedures done to any sample is important in ensuring the results can be reproduced and ensuring no deviations occurred, in turn potentially causing questionable results.
Last but not least: training. Laboratory staff should be well versed in any procedures they are involved in to ensure high data quality and integrity. If any laboratory staff does not receive appropriate training in any operating procedures, the data quality becomes suspect.
CIJ: What are some of the biggest obstacles or pitfalls cannabis labs face when trying to get accredited?
Steve: Not fully preparing to meet any agency and testing regulations and requirements will cause delays in the accreditation process and potentially more work for the laboratory. From documentation to daily operations, if any aspect becomes a major finding for an auditor, additional data is usually required to prove the error has been fixed satisfactorily.
Taking the time early on to ensure all documentation, processes and procedures are adhering to any regulatory agency requirements is important for a smooth accreditation process. It is easy to overlook small details when building out the operating procedures that might be essential in the process. Again, going back to data quality, the laboratory must ensure all steps are outlined and documented to ensure high quality (reproducible) data and integrity.
A new employee should be able to come in and read a quality manual and standard operating procedure and produce equivalent data to any laboratory analyst doing the same job. With difficult or challenging operating procedures it becomes even more important that training and documentation are adhered to.

A certified reference material (CRM) is generally recognized as providing the highest level of traceability and accuracy to a measurement. A CRM designed specifically for cannabis testing and tailored to state-specific testing regulations could help laboratories better ensure the safety of their products.
The fact that a certificate accompanies a reference material does not qualify it as a CRM. The reference material must be produced in accordance with ISO Guide 34 specifications by an accredited manufacturer. Adam Ross, key account manager and organic specialist at LGC Standards, says accreditation is a big part of bringing legitimacy to cannabis testing. “For a laboratory to receive an ISO 17025 accreditation, they must purchase their RMs from an ISO 17025 manufacturer. The best option is to purchase an ISO Guide 34 manufactured CRM,” says Ross. “It is particularly important for testing requirements, such as potency, pesticides, etc., where quantitation is expected, to use properly certified quantitative reference materials.” LGC Standards, a 175-year-old company, is one of those manufacturers that invested the time and money to achieve ISO Guide 34 accreditation and offers a spectrum of CRMs for cannabis testing.
The major advantage to using a proper CRM is an increased level of credibility. Auditors recognize the value of using a CRM which can add to the integrity of the results produced. The regular use of certified reference standards along with proper training, methodology and instrumentation, will facilitate a result that has the least amount of uncertainty and is more defendable. “The regular use of certified reference standards will help ensure products that go to market are safe to consume,” says Ross.
With regard to potency analyses, Ross has some key insights to help a laboratory better utilize CRMs. “My advice? Don’t mix the cannabinoids; labs analyzing by GC/FID have discovered that some of the cannabinoids will co-elute. Also, they have a short shelf life when mixed together,” says Ross. “Cannabinoid analysts should use GC/MS or LC/MS for their analysis or analyze the cannabinoids individually,” says Ross.
So what happens if a cannabis lab uses non-certified reference materials? Labs might save money in the short term. CRMs are slightly more expensive than a non-certified reference material, but will increase the defensibility of a lab’s data. Using a reference material created in-house or from a non-accredited vendor can lead to less-than-accurate results. A non-certified reference material has a greater chance of being made incorrectly. The publication of incorrect data damages the credibility of the testing lab and could lead to legal action against the lab from damaged parties.
One of the major challenges for the cannabis testing industry is the variation in state-to-state regulations. Ross says that Oregon’s regulations are pretty comprehensive and that other states should look to the Oregon Environmental Laboratory Accreditation Program (ORELAP) for guidance. According to Ross, ORELAP would like to see higher quality standards with legitimate traceability. Utilizing CRMs the correct way will help laboratories achieve greater accuracy.
Here are some tips for using CRMs appropriately:
Always bring your standards to room temperature before making a dilution.
Matrix matched calibration standards provide more accurate quantitation. Prepare standards in the solvent from extracted blank matrices.
Always bracket your analytical runs with continuing calibration verification standards. Proving that your instrument remained calibrated during the run gives your data more credibility.
Analytical chemists purchase CRMs for three primary uses in the testing lab:
To calibrate the instrument that will be used to perform the testing
To confirm the instruments continuing calibration throughout the analytical process
For analytical quality control or “spikes”
Typically, labs will spike known concentrations of the analytes of interest into a control sample and regular samples with the intent of testing analytical efficiency. Recoveries of analytes from the spiked control sample tell the chemist how well the analytical method is working. The spiked samples (matrix spikes) demonstrate to what extent the sample matrix (the consumable being tested) is influencing the results of the analytical procedure.
CRMs could be described as the nexus between cannabis testing results, the human element and the instrumentation used in an analysis. By using a cannabis-specific CRM, the cannabis testing community can demonstrate tangible improvements in accuracy and legitimacy.
I have been working with the chemical analysis side of the cannabis industry for about six years, and I have seen tremendous scientific growth on the part of cannabis labs over that time. Based on conversations with labs and the presentations and forums held at cannabis analytical conferences, I have seen the cannabis analytical industry move from asking, “how do we do this analysis?” to asking “how do we do this analysis right?” This change of focus represents a milestone in the cannabis industry; it means the industry is growing up. Growing up is not always easy, and that is being reflected now in a new focus on understanding and addressing key issues such as pesticides in cannabis products, and asking important questions about how regulation of cannabis labs will occur.
While sometimes painful, growth is always good. To support this evolution, we are now focusing on the contribution that laboratories make to the safety of the cannabis consumer through the generation of quality data. Much of this focus has been on ensuring scientifically sound data through regulation. But Restek is neither a regulatory nor an accrediting body. Restek is dedicated to helping analytical chemists in all industries and regulatory environments produce scientifically sound data through education, technical support and expert advice regarding instrumentation and supplies. I have the privilege of supporting the cannabis analytical testing industry with this goal in mind, which is why I decided to write a regular column detailing simple ways analytical laboratories can improve the quality of their chromatographic data right now, in ways that are easy to implement and are cost effective.
Anyone with an instrument can perform chromatographic analysis and generate data. Even though results are generated, these results may not be valid. At the cannabis industry’s current state, no burden of proof is placed on the analytical laboratory regarding the validity of its results, and there are few gatekeepers between those results and the consumer who is making decisions based on them. Even though some chromatographic instruments are super fancy and expensive, the fact is that every chromatographic instrument – regardless of whether it costs ten thousand or a million dollars – is designed to spit out a number. It is up to the chemist to ensure that number is valid.
In the first couple of paragraphs of this article, I used terms to describe ‘good’ data like ‘scientifically-sound’ or ‘quality’, but at the end of the day, the definition of ‘good’ data is valid data. If you take the literal meaning, valid data is justifiable, logically correct data. Many of the laboratories I have had the pleasure of working with over the years are genuinely dedicated to the production of valid results, but they also need to minimize costs in order to remain competitive. The good news is that laboratories can generate valid scientific results without breaking the bank.
In each of my future articles, I will focus on one aspect of valid data generation, such as calibration and internal standards, explore it in practical detail and go over how that aspect can be applied to common cannabis analyses. The techniques I will be writing about are applied in many other industries, both regulated and non-regulated, so regardless of where the regulations in your state end up, you can already have a head start on the analytical portion of compliance. That means you have more time to focus on the inevitable paperwork portion of regulatory compliance – lucky you! Stay tuned for my next column on instrument calibration, which is the foundation for producing quality data. I think it will be the start of a really good series and I am looking forward to writing it.
