Ion exchange chromatography (IEX) resins

Ion exchange chromatography (IEX) resins are commonly used to separate molecules, such as large proteins, small nucleotides, and amino acids, depending on their charge. The functional groups in the IEX resins have charges that bind the molecules with opposite charges. The release of the molecules bound to the resin is carried out by charge displacement, via the application of an increasing concentration of a molecule of the same charge.

Depending on the size of the beads, the pore size, the functional groups and the mechanical strength of the individual base matrices, our IEX resins can be used to capture bulk products or impurities from large volumes , as an intermediate step or as a final step for high resolution purifications.

We offer a wide range of ion exchange chromatography media (resins). Depending on the nature of your application, the property of your raw material and the resolution you need, you will find the right resin for you.
