Gc Ms Testing

Gas chromatography-mass spectrometry (GC-MS) is an analytical chemistry technique used to identify and quantify volatile compounds in cannabis samples, particularly terpenes and residual solvents. Rather than an aroma descriptor itself, GC-MS serves as the laboratory instrument that profiles the actual aromatic and chemical composition of a strain. Breeders and labs use GC-MS data to objectively document terpene profiles—such as limonene, myrcene, or pinene percentages—rather than relying on subjective sensory notes. This methodology has become standard in regulated cannabis markets for quality assurance, potency verification, and detection of contaminants. Understanding GC-MS results helps breeders select parent plants with consistent aromatic and chemical traits across generations.

Breeders use GC-MS profiles as objective selection criteria when stabilizing strain genetics, allowing them to identify and preserve plants with reproducible terpene expressions. Detailed chromatography data also enables breeders to verify strain authenticity and track genetic drift across cultivation cycles.
