GC: Gas Chromatography

Gas Chromatography (GS) is a technique that vapourises a substance or mixture to separate its individual compounds from one another.

When cannabis undergoes gas chromatography its cannabinoids, flavonoids and terpenes are isolated in their pure form and chemists can calculate the potency and concentration of these elements. This type of chromatography involves passing an inert or unreactive gas through cannabis in order to extract its contents.
