Flash chromatography is a separations technique that is incredibly useful in a swath of scientific practices. In the hemp and cannabis industry, flash chromatography is used primarily as a remediation method that removes products from an extract that cannot legally, or safely remain in the end product. Delta 9 THC, for example, is a legal issue in hemp based extracts that must be remediated to create a legal product. Because federal law requires that delta 9 THC levels do not exceed 0.3%. This makes the method of flash chromatography incredibly important to remove excess levels of delta 9 THC and other psychoactive cannabinoids from a hemp product so that it is safe and legal. In this episode of extrakTALKS, Dr. Jon and Randall Thompson talk about flash chromatography and how it is used in the extraction industry today.
