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.

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 first launched solid phase microextraction (SPME) automated sample preparation fibers to reduce sample handling and solvent consumption in many industries, such as environmental, food, and clinical. Soon after came rugged Restek PAL SPME Arrows, a revolution in microextraction that combines exceptional robustness with faster extraction times and trace-level sensitivity. Now, both fiber and Arrow lines are being expanded, including the addition of a sought-after triple-phase offering.
Of significant interest to many analysts, new triple-phase SPME fibers and Arrows provide exceptional versatility. This divinylbenzene (DVB)/carbon wide range (WR)/polydimethylsiloxane (PDMS) combination can be used for quick and efficient extraction of a wide range of both volatiles and semivolatiles, and it is an excellent choice for decision-making during method development because it combines the characteristics of three popular phases.
Restek’s full SPME line of fibers, Arrows, and accessories can be found at www.restek.com/SPME
Restek’s support for cannabis-testing labs continues to grow. This latest offering will help you meet the specific cannabis analysis needs of California set forth by the Bureau of Cannabis Control for regulated category I and II residual pesticide reporting—and of other states with similar regulations/programs. Ideal for creating multipoint (5-point minimum suggested) calibration curves for GC- and LC-MS/MS, these six mixes of prepared stock standards also eliminate the need for in-house standards preparation. And, as with all certified reference materials (CRMs) manufactured and QC tested in Restek’s ISO-accredited labs, they will satisfy your ISO requirements.
