5-Part Cannabinoid Potency
Testing packages are available. All results are strictly confidential.
PSI uses Supercritical fluid chromatography (SFC) to perform Cannabinoid Potency tests. SFC is the most reliable and accurate form of testing available. Because no heat is involved in the process, SFC is able to distinguish between naturally occurring acidic and neutral compounds.
Gas Chromatography (GC) is used for Terpene Profiling. GC is appropriate for separating and analyzing compounds that can be vaporized without decomposition, such as the essential oils in terpenes and volatile chemical residues.
*Cultivators must be registered with the Vermont Agency of Agriculture. Dispensaries must be registered with the Vermont Marijuana Registry.
