Gas Chromatography Gc Ms

Gas Chromatography-Mass Spectrometry (GC-MS) is an analytical laboratory technique used to identify and quantify volatile organic compounds in cannabis plant material and concentrates. The method separates terpenes and other aromatic molecules based on their chemical properties, then identifies them by mass signature. GC-MS data provides objective, reproducible profiles of cannabinoid and terpene composition—information that helps breeders and researchers understand strain chemistry beyond subjective aroma descriptors. This technique has become standard in cannabis testing labs and breeding programs seeking chemical consistency and lineage verification.

Breeders use GC-MS profiles to objectively track terpene inheritance across generations, identify novel chemotypes, and verify strain authenticity. Consistent GC-MS signatures help establish stable chemotypes within breeding lines and support selective breeding for specific aromatic and chemical traits.
