Abstract

A flash chromatography apparatus which provides an improved apparatus for large and medium commercial scale flash chromatography columns. More particularly, the invention relates to a flash chromatography column and cartridge system for positioning and ease of loading and unloading of stationary phase agent in the flash chromatography column. The flash chromatography column further provides flow distributors to support the stationary phase and permit plug flow through the column. The apparatus of the present invention is a modular and can be disposed in any configuration to reduce maintenance cost and downtime in a commercial installation. Flash chromatography is widely used for purification of low molecular weight organic compounds and products of organic synthetic reactions.
