Gc Analysis

Gas chromatography (GC) analysis is a laboratory technique used to separate and identify volatile aromatic compounds in cannabis plant material. This analytical method measures the presence and concentration of terpenes, esters, and other odorant molecules by vaporizing samples and passing them through a specialized column. GC analysis provides objective, quantitative data about aroma profiles—complementing subjective sensory evaluation. Breeders and researchers commonly employ GC-FID (flame ionization detection) or GC-MS (mass spectrometry) to profile strain aromatic chemistry and track genetic consistency across generations. Understanding the chemical composition revealed by GC helps differentiate cultivars and supports reproducible breeding programs.

Breeders use GC analysis to document terpene phenotypes within strain families, ensuring selected plants maintain consistent aromatic profiles across crosses. This data-driven approach allows precision tracking of aromatic traits through multiple generations and supports informed parent selection for targeted aroma expression.
