Chromatographic Analysis

Chromatographic analysis refers to laboratory techniques used to separate and identify individual terpenes and cannabinoids within cannabis samples. Gas chromatography (GC) and liquid chromatography (LC) are the most common methods employed in cannabis testing, allowing chemists to quantify specific aromatic compounds and volatile organic molecules present in plant material. These analytical methods provide objective data about a strain's chemical profile, independent of sensory perception. Chromatography is foundational to breeding programs seeking to stabilize or enhance particular terpene ratios, and to quality assurance workflows in regulated markets. Understanding chromatographic profiles helps distinguish between chemovars with similar aromas but different underlying terpene compositions.

Breeders use chromatographic data to identify and select parent plants with consistent, desired terpene profiles across generations. By analyzing offspring and comparing results to parental samples, breeders can predict inheritance patterns of specific volatile compounds and refine phenotype selection more precisely than sensory evaluation alone.
