Advance Your Analysis of Cannabis With Our New Cannabidivarinic Acid (CBDVA) Standard

Cannabidivarinic Acid (CBDVA) is a non-psychoactive cannabinoid reported to have anti-inflammatory properties. While its medicinal benefits are still being researched, quantifying this compound in cannabis samples is crucial for obtaining a true measurement of potency and chemovar identification. Restek now offers a new CBDVA certified reference material (CRM) to help labs advance their analysis of cannabis.

Restek’s new CBDVA standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC analysis. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As it’s excluded from U.S. DEA Controlled Substances Act (CSA) regulatory controls, no customer permits or licensing required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBDVA standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

Analysis of Pesticides and Mycotoxins in Cannabis Brownies

Author: Nathaly Reyes and Colton Myers

Published By: Restek Corporation

Year of Publication: 2020

Link: https://www.restek.com/Technical-Resources/Technical-Library/Foods-Flavors-Fragrances/fff_FFAN3149-UNV

Abstract: Government regulations in California require the cannabis industry to test edible products for an extensive list of pesticides and mycotoxins. Here, an effective workflow for this complex analysis was developed in brownies and optimization strategies are detailed in order to provide a starting point for similar matrices. Both LC-MS/MS and GC-MS/MS were employed and excellent results for LOQ, linearity, accuracy, and precision were attained for all the target compounds.

Fast, Low-Solvent Analysis of Cannabinoids Increases Lab Productivity and Decreases Solvent Costs

Published By: Restek Corporation

Year of Publication: 2019

Link: https://www.restek.com/Technical-Resources/Technical-Library/Foods-Flavors-Fragrances/fff_FFSS3123-UNV

Abstract: Suitable for high-throughput cannabis testing labs, this LC-UV method reliably separates 19 cannabinoids in a quick, 10-minute analysis. Using only 3 mL of acetonitrile per run, labs can significantly decrease solvent use and the associated costs by adopting this procedure.

Attain a More-Comprehensive Characterization of Cannabis Samples with Restek’s New Cannabicyclol (CBL) Reference Standard

Cannabicyclol (CBL) is formed through the photodegradation of cannabichromene (CBC). Levels are typically quite low, and the medicinal benefits of CBL are still being researched, but quantifying this compound in cannabis samples is crucial for obtaining a more-complete cannabinoids profile. Restek has just released a new CBL certified reference material (CRM) to further aid labs in the comprehensive characterization of cannabis: www.restek.com/catalog/view/54615

Restek’s new CBL standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC analysis. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As a U.S. DEA-exempted formulation, no additional customer permits or licensing are required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBL standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

Cannabidivarin (CBDV) Added to Restek’s Selection of Cannabis Reference Standards

Cannabis strains with high levels of cannabidiol (CBD) typically have higher levels of cannabidivarin (CBDV) as well, but accurate quantitation of both compounds for potency and strain ID is a must, especially as interest in using CBDV as an anticonvulsant and anti-nausea treatment continues to rise. Restek now offers a stand-alone CBDV reference standard—in addition to CBD and a host of other compounds—to help labs with the comprehensive analysis of cannabis products.

Restek’s CBDV standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC-MS/MS. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As a U.S. DEA-exempted formulation, no additional customer permits or licensing are required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBDV standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

Restek Employee-Owner Joins Editorial Board of Influential Cannabis Science Publication

Ashlee Gerardi joins Cannabis Science and Technology in an effort to advance the science of safety and potency testing in this growing industry

A new industry has bloomed, offering scientists a rare opportunity to build a field from the ground up, and Restek has already been helping.

In addition to Restek’s cannabis-specific products, applications, and support for cannabis testing labs, Ashlee Gerardi, Associate Business Development Manager at Restek, has joined the editorial advisory board of Cannabis Science and Technology. In her role, she will review articles submitted to the publication and provide additional insight and information on the cannabis testing industry by attending conferences and participating in trade association focus groups.

“I’m looking forward to advancing cannabis science and helping to ensure quality education continues to be found in the magazine,” she said. “Teaching this audience the fundamentals of chemistry and chromatography is vital to testing in this growing industry.”

Gerardi joined Restek in 2011, moving to Restek’s California office in 2013 as an R&D chemist. However, the demand for an additional business development manager was soon needed for the growing cannabis analysis industry, and Ashlee was eager to use her technical background and business knowledge to help Restek’s cannabis customers as an associate business development manager for the cannabis testing industry.

“Because the landscape is rapidly changing, one of the fastest-growing needs of the cannabis market is legitimacy. Our team at Restek provides consumables as well as testing solutions for product quality, potency, and safety analyses in the market,” she said.

Gerardi said the cannabis industry has a lot to offer adventurous scientists, as “there is still much of the cannabis plant that needs to be understood along with analytical challenges/pain points that remain to be solved,” adding that “Restek is supported by many knowledgeable scientists whom I interact with daily. Our team is constantly working to solve analytical pain points such as potency, terpenes, mycotoxins, residual solvents, and pesticide testing.”

By way of example, Ashlee noted that the recent November/December edition of Cannabis Science and Technology, Restek’s Justin Steimling, LC Solutions Applications Manager, wrote, “If product labels are to accurately reflect cannabinoid content, the complete sample composition must be considered in developing a robust and accurate analytical method.”

Gerardi said she keeps up with the wealth of cannabis knowledge through publications like Cannabis Science and Technology, but also through conferences and social media.

Gerardi still sees a lack of legitimacy in the cannabis market but says, “Restek is proud to have helped cannabis labs establish sound analytical practices from the beginning, and we will continue to be there for you every step of the way as the testing landscape changes.” In September 2019, she will attend the annual Cannabis Science Conference in Portland, OR, where she plans to give an oral presentation.
