• Jul 16, 2018 · Flash chromatography is “a type of rapid preparative column chromatography where 0.1 – 10 g of mixture is separated in less than 15 minutes by using pressurized gas to drive the mobile phase through the column.” In flash chromatography, gravity or some external source of pressure pushes the mobile phase through the column which is packed with a solid stationary phase. The cannabis compounds interact with the solid stationary phase for differing amounts of time, and are eluted in order ...

The separation occurs based on the differences in the polarity of the analytes. The analytes that interacts most in the stationary phase will elute later than the analytes that interact least in the stationary phase. Reversed phase chromatography is used in which the stationary phase is non-polar while the mobile phase is the polar mixture.
