Gas Chromatography Analysis

Gas chromatography (GC) analysis is a laboratory technique used to separate and identify volatile compounds in cannabis plant material and extracts. By heating a sample and passing it through a column, GC separates cannabinoids, terpenes, and other volatile molecules based on their chemical properties, allowing researchers to create a precise chemical fingerprint. This method is commonly paired with mass spectrometry (GC-MS) to confirm compound identity and measure concentration levels. GC analysis has become standard in breeding programs and quality assurance workflows for understanding strain chemistry. However, GC measures only volatile compounds and may not capture the full spectrum of non-volatile cannabinoids present in raw plant material.

Breeders use GC analysis data to track terpene and cannabinoid inheritance patterns across generations, helping identify which parent plants contribute specific aromatic or chemical profiles. This quantitative approach supports selective breeding for consistency and allows breeders to document and distinguish strain families based on reproducible chemical markers rather than subjective observation
