Gas Chromatography Analysis

Gas chromatography (GC) is an analytical chemistry technique used to separate and identify volatile compounds in cannabis plant material. This laboratory method heats plant samples to vaporize their chemical constituents, then passes them through a column where compounds separate based on their boiling points and interactions with the column's stationary phase. Detection systems identify individual compounds, producing a chromatogram that maps the presence and relative abundance of terpenes, cannabinoids, and other volatile molecules. GC analysis provides reproducible, quantitative data about a strain's chemical profile—information increasingly referenced in breeding documentation and strain lineage records. While GC itself doesn't directly describe a consumer-facing aroma, the data it generates informs how breeders understand and select for specific terpene combinations and volatile com

Breeders and seed producers use GC analysis to verify and document the chemical consistency of stable lines and to identify phenotypic variants within a strain family. This analytical backbone helps ensure that genetic selection targets can be measured objectively rather than relying on subjective aroma assessment alone.
