Modular Multiple-Column Chromatography Cartridge

摘要

A method for liquid chromatography comprises steps of: mixing a sample comprising a plurality of chemical constituents with a first solvent; transferring the solvent and the plurality of constituents to a first chromatographic column housed in a cartridge; chromatographically separating a sub-group of the plurality of constituents from unwanted constituents using the first chromatographic column; transferring the sub-group of the plurality of constituents from the first chromatographic column to a second column housed in the cartridge, the transferring effected by the flow of a second solvent; chromatographically separating, from one another, individual constituents of the sub-group of the plurality of constituents using the second chromatographic column; and transferring the separated individual constituents to a detector.
