Chromatography Troubleshooting in the Cannabis Lab

Before it can be legally sold in dispensaries, cannabis products have to tested for a range of potency markers and contaminants, including cannabinoids, terpenes, mycotoxins, pesticides, residual solvents, and heavy metals. Gas chromatography (for cannabinoid, terpene, and pesticide analysis) and liquid chromatography (for cannabinoid and mycotoxin analysis) is often used to achieve this testing.

But each of these techniques come with few common problems. In order to help cannabis analysts, this Analytical Cannabis How to Guide explains how to recognize and solve common chromatographic problems when analyzing terpenes and cannabinoids.
