Potency testing looks at the total amount of cannabinoid content, including tetrahydrocannabinol (THC) and other phytocannabinoids such as cannabidiol (CBD), cannabigerol (CBG), and tetrahydrocannabivarin (THCV). Potency testing is typically performed by liquid chromatography with UV detectors to determine the amount of major cannabinoids. However, analysis of trace and minor cannabinoids is becoming more common with mass spectrometry. To test potency of oils, crude extracts, and distillates, FTIR spectroscopy is often used in production and manufacturing environments.
