The technique is sufficiently simple and powerful that a beginner can successfully resolve diastereomers on sample scales ranging from 100 mg to 1 g. Since its description in 1978, flash column chromatography anslysis has become a routinely used tool to separate fine chemicals in the organic laboratory. For example, pure R-amino acid-N-carboxyanhydride (NCA) monomers which are the widely used precursors for the synthesis of polypeptides, can be obtained using the flash column chromatography, without the need for recrystallization.
Advantages of Flash Column Chromatography
Traditional column chromatography is an important purification separation method used in many laboratories. Unlike flash column chromatography, it can be very time consuming and labor intensive though. Flash column chromatography systems speed up the process by using pressurized gases to rapidly move eluents through the column. These column separation solutions can pump as many as four types of solvents at rates up to 250ml/min, at up to 10bar/145psi. A flash chromatography system typically uses a UV or IR detector, perfect for precisely analyzing separation peaks. Besides, the flash column chromatography systems can be reconfigured due to their modular design.

Macroporous Adsorption Resin
Macroporous adsorption resin uses a special adsorbent to selectively adsorb the active ingredient from compound decoction of crude drugs, and remove the invalid component. The method is simple in equipment, convenient in operation, energy-saving, low in cost, high in product purity, and non-hygroscopic. Therefore, the technology has been widely used for the purification of glycosides, flavonoids, and alkaloids.
