Gas Chromatography Ms

Gas Chromatography-Mass Spectrometry (GC-MS) is an analytical laboratory technique that separates and identifies volatile compounds in cannabis plant material. The method combines gas chromatography's separation capability with mass spectrometry's compound identification, producing a chromatogram that displays individual chemical constituents and their molecular weights. GC-MS is commonly used in cannabis research and quality control to profile terpenes, residual solvents, and other volatile organic compounds. The technique requires samples to be vaporized, making it particularly suited for analyzing the aromatic and more volatile fraction of cannabis chemistry. Lineage records and breeding documentation often reference GC-MS data when reporting terpene profiles across generations. Understanding GC-MS results is foundational for breeders tracking chemical consistency in strain lines.

Breeders use GC-MS data to objectively document terpene profiles across parent lines and progeny, supporting selective breeding for consistent aromatic and volatile chemistry. Comparative GC-MS analysis helps identify which genetic backgrounds reliably produce target terpene ratios.
