Gas Chromatography Fid

Gas Chromatography with Flame Ionization Detection (GC-FID) is an analytical chemistry method used to separate and identify volatile compounds in cannabis samples. The technique vaporizes cannabinoid and terpene molecules, separates them by boiling point through a heated column, and detects them via ionized flame response. GC-FID has been widely adopted in cannabis breeding research and quality control to quantify THC, CBD, and major terpene profiles without requiring additional chemical derivatization. This method is particularly useful for establishing baseline chemical phenotypes across strain lineages and seed populations, though results can vary based on sample preparation and instrument calibration standards.

Breeders and seed companies use GC-FID data to document chemotype consistency within strain families, track terpene expression across generations, and validate claimed cannabinoid ratios in parent stock. Standardized GC-FID profiling enables more reproducible seed selection and lineage documentation.
