High Performance Liquid Chromatography Hplc

High-Performance Liquid Chromatography (HPLC) is an analytical laboratory technique used to separate, identify, and quantify cannabinoids and terpenes in cannabis plant material. The method forces a liquid sample through a pressurized column packed with specialized stationary phase material, allowing compounds to separate based on their chemical properties and affinity for the column medium. HPLC is commonly employed in cannabis testing labs to measure cannabinoid profiles (THC, CBD, CBN, etc.) and to detect residual solvents or contaminants. Unlike gas chromatography, HPLC does not require heat, making it suitable for analyzing heat-sensitive compounds. Breeders and cultivators rely on HPLC data to verify strain composition, track genetic stability across generations, and confirm seed or clone authenticity.

Breeders use HPLC test results to objectively document cannabinoid and terpene ratios in parent plants and offspring, supporting selection decisions for consistent lineages. Accurate HPLC profiles help distinguish between phenotypic variations within a strain family and validate cross-breeding outcomes.
