Weak Cation Exchangers

With weak cation exchange media the degree of dissociation and thus ion exchange capacity varies with pH. Therefore, it is more critical to optimize the pH if weak cation exchange media is used.

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.
