Ion Exchange

Ion-exchange (IEX) chromatography media is popularly employed to separate molecules, such as large proteins, small nucleotides and amino acids etc, based on their charge. The functional groups in IEX media have charges that bind molecules with opposite charges. Release of the bound molecules from the medium is achieved by displacement, via the application of an increasing concentration of a similarly charged molecule.

By design of the bead size, pore size, functional groups and the mechanical strength of individual base matrices, our IEX media can be used for capture of bulk product or impurities from large-volumes, as an intermediate purification step, or as a final step for high resolution purifications.

We offer an extensive range of ion exchange chromatography media (resins) in lab packs, bulk quantities and prepacked columns.
