Cannabis potency testing can be performed using high performance liquid chromatography (HPLC) or gas chromatography (GC), each having its advantages. GC is a quick and convenient method compared to HPLC, and may be a major determining factor in choosing a system. However, GC cannot detect CBDA, THCA, and other acids. These acids require an HPLC system for analysis. During a GC operation, the injector heats up the sample, causing decar-boxylation. In this process, THCA is converted to THC, and CBDA to CBD. Heating by the GC can simulate the smoking or baking process, commonly performed on cannabis products. This conversion does not affect the total THC and total CBD analysis, although the amount of THCA in cannabis can be desirable as its effects are different than those of THC.
