THC can be analyzed by GC directly, but because THCCOOH contains an ,acid, group in its structure it requires derivatization. Thus, if the two compounds are analyzed together, derivatization must be used. Silylation can be used to produce GC-stable derivatives of both THC and THCCOOH.

Current Practice in GC-MS Analysis of Organics in Water

Extraction The first step in GC-MS analysis is extraction of the organic compounds from the bulk of the water. Commonly, a liter sample of water is extracted with two or three 50 to 100-ml portions of solvent. The combined extracts are dried and the solvent is evaporated to 1 ml or less for GC analysis.
