Total potency testing determines the concentrations of tetrahydrocannibinol (THC), cannabidiol (CBD) and cannabinol (CBN). The THC:CBD ratio impacts end usage of the product, pricing and taxation, while the presence of significant amounts of CBN indicates product degradation due to improper storage or ageing. The acidic precursors THCA and CBDA, found in fresh plant material and extracts, are decarboxylated to neutral THC and CBD species during GC analysis making this method an excellent means of providing rapid THC and CBD total potency results.
The G908 analyzer quickly identifies and quantifies THC, CBD, CBN and other neutral cannabinoid species in cannabis extracts at the push of a button. A ballistically heated capillary column provides ultrafast separation of all cannabinoids while flame ionization detection (FID) confirms component identification by retention time and automatically calculates the concentrations for all detected species.
