All cannabinoids listed are tested using High Pressure Liquid Chromatography – Diode Array Detection (HPLC-DAD)
Cannabinoids are the terpeno-phenolic compounds unique to Cannabis that give the herb its multitude of medicinal properties. Cannabinoids are odourless and flavourless compounds located in the trichomes of leaves and mature flowers. It is the terpenes that give the plant aroma and flavour. There are many (over 100 discovered) different cannabinoids found in various quantities in different strains of Cannabis. The variations of cannabinoids and terpenes present in a given strain gives that strain its unique effect, taste and smell.
The most abundant cannabinoids, and their carboxylic acids, known to have medicinal properties, are tested for in our laboratory. Our professional lab technician uses High Pressure (Performance) Liquid Chromatography (HPLC) technology to detect and quantify specific cannabinoids using known analytical standards.
The process begins with a dry-weight determination of the cannabis sample, then cannabinoid extraction into a solvent using sonication and centrifugation and finally injection into the HPLC. The resulting graph is compared to known cannabinoid standard solutions.
