Chromatographic Testing

Chromatographic testing refers to laboratory analytical methods used to separate and identify cannabinoid and terpene profiles in cannabis samples. These techniques—including gas chromatography (GC), liquid chromatography (LC), and high-performance liquid chromatography (HPLC)—provide quantitative data on chemical composition without relying on sensory evaluation. Breeders and seed banks use chromatographic data to document cannabinoid ratios, minor cannabinoid presence, and terpene concentrations across generations. This analytical approach enables objective comparison of genetic expression and chemical stability across cultivars and breeding lines. Chromatographic results form the foundation of modern cannabis genetics documentation, allowing breeders to track trait inheritance and chemical consistency.

Breeders employ chromatographic testing to verify cannabinoid ratios in stabilized lines, identify minor cannabinoid-rich phenotypes (CBD, CBG, CBN), and document terpene expression patterns. This data supports selective breeding decisions and helps establish reproducible chemical markers for cultivar registration and seed stock preservation.
