Gc Ms Chromatography

Gas chromatography-mass spectrometry (GC-MS) is an analytical technique used to identify and quantify volatile and semi-volatile compounds in cannabis samples, including cannabinoids and terpenes. This laboratory method separates chemical components by heating them to vapor form, then measures their molecular weight and fragmentation patterns. GC-MS is commonly employed in breeding programs and quality assurance to establish cannabinoid and terpene profiles across generations. The technique requires samples to withstand high temperatures, which can alter heat-sensitive compounds like certain terpenes. Breeders and researchers use GC-MS data to track trait inheritance, verify genetic stability, and document chemical phenotypes within strain families. Understanding GC-MS results helps establish breeding benchmarks and inform strain classification efforts.

Breeders use GC-MS profiling to objectively document and compare cannabinoid and terpene ratios across parent plants and offspring, supporting selective breeding decisions. Standardized GC-MS data enables lineage documentation and helps identify stable chemical phenotypes worth preserving or hybridizing.
