Gc Ms Analysis

Gas chromatography-mass spectrometry (GC-MS) is an analytical laboratory technique used to identify and quantify volatile organic compounds in cannabis plant material, including terpenes, residual solvents, and other chemical constituents. Unlike sensory description, GC-MS provides objective, reproducible chemical profiles by separating compounds through gas chromatography and detecting them via mass spectrometry. Breeding programs and regulatory testing often employ GC-MS to verify terpene composition, establish chemical fingerprints for strain identity, and screen for unwanted contaminants. This data-driven approach complements traditional phenotypic observation, allowing breeders to track inherited chemical traits across generations and correlate genotype with chemotype.

Breeders use GC-MS results to select parents for consistent terpene profiles, confirm chemotype stability in crosses, and document chemical diversity within strain families. Regulatory compliance and seed-bank curation increasingly rely on GC-MS verification to distinguish phenotypic variants and validate claimed lineages.
