Volatile Compound Gas Chromatography

Volatile Compound Gas Chromatography (GC) is an analytical technique used to separate and identify aromatic compounds in cannabis plant material. The method heats samples to vaporize volatile molecules, then passes them through a column to isolate individual components based on their chemical properties. GC analysis commonly identifies terpenes, esters, and other low-molecular-weight compounds that contribute to strain aroma profiles. This laboratory method provides quantitative and qualitative data on cannabinoid and terpene composition, helping breeders and researchers document strain chemistry. GC results are often cross-referenced with sensory evaluation to understand how volatile profiles correlate with observable plant characteristics.

Breeders use GC data to select parent plants with desired aromatic profiles and to document how volatile compound expression varies across generations. Understanding terpene and ester profiles through GC analysis helps geneticists track stability and consistency in strain development.
