Gas Chromatography Gc

Gas chromatography (GC) is an analytical laboratory technique used to separate and identify volatile compounds in cannabis plant material and finished products. In cannabis science, GC instruments detect terpenes, residual solvents, pesticides, and other volatile organic compounds by vaporizing samples and measuring their movement through a stationary phase. This method provides quantitative data on chemical composition and is commonly referenced in cannabis testing standards and breeding documentation. GC analysis helps breeders and producers understand aromatic profiles and verify product purity, though it differs from sensory evaluation or field observation. Understanding GC data literacy supports informed discussion about strain chemistry and cannabinoid/terpene ratios in cannabis genetics literature.

Breeders consult GC testing results to track terpene expression across generations and select for desired volatile compound profiles. GC data informs decisions about phenotype selection and helps document the chemical fingerprints of established strain families.
