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.

Restek to Present “Gas Chromatography: Foundation Theory, Column Selection, and Troubleshooting” at GC-MS Seminar

Chromatographers from Restek will be presenting at Waters’s upcoming seminar on October 23, 2019, in Wood Dale, IL. This educational opportunity is aimed at scientists looking to learn more about GC-MS capabilities in all areas, particularly in food and environmental applications. Topics include the technology behind GC-MS instruments, QuEChERS sample preparation, identification of extractable and leachable compounds from electronic cigarettes, and multiresidue pesticide analysis. Register today and join us for an outstanding technical training event.

Abstract: Dietary supplements, which are consumed worldwide, are made from various botanical ingredients. To be safe from pesticides exposure, residual pesticides must be monitored by chromatographic instrumentation. Issues arise, however, due to the fact these botanical samples are dried and cause large interferences in the chromatography. This study shows that the modified QuEChERS method combined with GC-MS/MS achieves consistent pesticides monitoring in botanical ingredients.
