Liquid Chromatography Hplc

High-Performance Liquid Chromatography (HPLC) is an analytical technique used to separate, identify, and quantify cannabinoids and other compounds in cannabis plant material and extracts. The method forces a liquid sample through a pressurized column containing a stationary phase, allowing different molecules to separate based on their chemical properties and interaction with the column material. HPLC is widely regarded in cannabis testing labs as a reference standard for cannabinoid profiling, offering high precision and repeatability. Unlike gas chromatography, HPLC does not require heat, making it suitable for analyzing heat-sensitive compounds. Breeders and seed producers rely on HPLC data to verify cannabinoid ratios in parent plants and offspring, establishing accurate lineage records.

Breeders use HPLC results to confirm cannabinoid phenotypes in breeding stock, helping establish true CBD-dominant, THC-dominant, or balanced cultivars. Accurate HPLC profiles enable breeders to track genetic stability across generations and validate claimed chemotypes in seed catalogs.
