Terpene Analysis Gc Ms

Gas chromatography-mass spectrometry (GC-MS) is an analytical technique used to identify and quantify individual terpenes and volatile compounds in cannabis samples. This method separates complex mixtures into distinct molecular components, then ionizes them for mass-based detection, producing a chemical profile rather than marketing claims. GC-MS results reveal the actual terpene composition—limonene, myrcene, pinene, and dozens of others—without subjective interpretation. Breeders and researchers rely on GC-MS data to verify chemotype stability across generations and to document the chemical baseline of their lines. This classification reflects laboratory rigor rather than sensory assessment, making it a foundational tool for objective cannabis genetics documentation.

Breeders use GC-MS profiling to confirm terpene expression consistency within a cultivar, identify genetic markers for specific compound ratios, and validate whether offspring match parent plants. Accurate terpene data supports selective breeding for stable chemotypes and informs decisions about crossing lines with complementary volatile profiles.
