Unsurprisingly, Cannabinoids are the most common analytes tested for in cannabis and hemp. There are two types of equipment used by labs to test cannabinoids: High-performance liquid chromatography (HPLC) and gas chromatography (GC).

What is the Difference Between HPLC and GS Testing?

While each has their pros and cons, the HPLC is the hemp and cannabis potency testing gold-standard due to it's speed and ability to measure the largest spectrum of cannabinoid analytes.

GC is less commonly used for testing potency in cannabis and hemp. You will most often see this method used in cases where a long list of cannabinoids isn't needed. The largest difference is that a GC will decarboxylate all acid-cannabinoids in its measurement process. The outcome is that you end up with single result for the total of the acid and neutral cannabinoid (e.g. a single result for total THC instead of separate results for THC and THCa.) One benefit of the GC is that you can also test for terpenes on a system configured for cannabinoid analysis!
