New THCV Standard for Medical Cannabis Testing

Analyze medical cannabis samples more easily and accurately with Restek’s new tetrahydrocannabivarin (THCV) standard. This new certified reference material (CRM) is DEA-exempted and reduces the time, expense, and variability associated with preparing standards directly from neat material. Verified in composition and stability, Restek’s THCV standard is manufactured and QC-tested in ISO-accredited labs to ensure quality and satisfy ISO requirements. Our THCV CRM was developed to improve LC and GC methods for medical cannabis potency testing and strain identification. It is the latest addition to Restek’s suite of products for medical cannabis analysis including potency, strain ID, terpenes, pesticides, and residual solvents test methods.
