Gc Ms Detection

GC-MS detection refers to gas chromatography-mass spectrometry, an analytical laboratory technique used to identify and quantify cannabinoids, terpenes, and other volatile compounds in cannabis plant material. This method separates chemical compounds by heating a sample, then identifies them through mass spectrometry—a process that ionizes and fragments molecules to create a unique fingerprint. GC-MS is considered a gold-standard reference method in cannabis testing because it provides precise molecular identification and is widely used in regulatory compliance labs, breeding programs, and research institutions. The technique works best for thermally stable compounds but requires careful sample handling to avoid degradation of heat-sensitive molecules like some minor cannabinoids. Breeders and seed banks often reference GC-MS data when documenting cannabinoid and terpene profiles across

Breeders use GC-MS data to verify cannabinoid ratios and terpene compositions in parent plants and F1 crosses, enabling more precise phenotype selection and lineage documentation. Accurate GC-MS profiles help breeding programs track genetic stability across generations and distinguish similar chemotypes.
