Gas Chromatography Testing

Gas chromatography (GC) is an analytical laboratory technique used to separate and identify volatile compounds in cannabis samples, particularly cannabinoids and terpenes. The method vaporizes a sample and passes it through a heated column, allowing individual compounds to separate based on their chemical properties and travel time. GC analysis commonly reports cannabinoid profiles (THC, CBD, CBN, etc.) and terpene composition, though it does not directly measure potency or provide psychoactive effect data. In regulated cannabis markets, GC testing serves as a foundational tool for product labeling and batch documentation. Breeders and seed banks reference GC data to track chemical consistency across generations and to document strain lineage profiles.

Breeders use GC testing results to verify cannabinoid and terpene inheritance patterns, confirm chemical stability in stabilized lines, and document the chemical signature of parent plants when creating new crosses. Consistent GC profiles across generations help breeders establish reproducible strain families and support seed banking records.
