Chromatographic Profiling

Chromatographic profiling is a laboratory analytical technique used to separate and identify individual cannabinoids and terpenes within cannabis plant material. Common methods include high-performance liquid chromatography (HPLC), gas chromatography (GC), and liquid chromatography-mass spectrometry (LC-MS). These techniques break down the plant's chemical composition into measurable compounds, providing reproducible data on cannabinoid ratios, terpene abundance, and trace elements. Breeders and researchers rely on chromatographic data to document strain genetics and verify compound consistency across generations. This classification sits at the intersection of laboratory science and genetics documentation, enabling objective comparison of chemotype expression across cultivars.

Breeders use chromatographic profiles to select parent plants with target cannabinoid and terpene ratios, track chemotype stability across seed lines, and verify that offspring express intended genetic traits. Detailed chromatographic records establish baseline profiles that help distinguish phenotypic variation from true chemotypic drift.
