Certified Reference Standards (CRM)
This category holds 18 certified reference materials from Cayman Chemical, most supplied in 1mL ampules. Chemical CRM mixtures cover terpenes, residual solvents, mycotoxins and heavy metals, the last in a 30mL solution. Acids and neutrals mixtures are listed too. Single cannabinoid CRMs, including CBDVA, CBNA, THCV and THCVA-A, come at 1 mg/mL in acetonitrile or methanol.
Each standard CRM supports cannabis potency testing or residual solvent analysis by GC. When choosing, match the solvent to the method, confirm concentration and ampule volume, and check for ISO 17034 certification. To plan your calibration approach, read internal vs external calibration: pros and cons.
