A Quick Study ‐ Comparison of Chromatography Normal Phase vs. Flash on the Gilson PLC 2020
21 Mar 2012This application note provides a quick comparison of three pharmaceutical compounds using high pressure normal phase and low pressure flash chromatography. Comparison of peak shape, peak retention time, chromatography run time, fraction volume, and solvent consumption were all studied to determine the most efficient and optimal chromatography method.

Flash ChromatographyFlash chromatography is a fast-preparative column chromatography technique used for separation and purification of liquid analytes. Flash chromatography systems use small silica gel particles for separation and a pressurized gas for driving the solvent through the column or pre-packed cartridge.

This can be done in large quantities or small. Preparative chromatography systems are usually low to medium pressure liquid chromatographs that are semi-automated.
