The ProtEx columns are specifically designed to have lowest non-specific adsorption and high resolution for protein purifications. ProtEx columns are packed with a 5 µm resin and available as strong cation exchanger (SP) and weak anion exchanger (DEAE). The CQA and CQK series of columns are high performance columns based on 10 µm bead size polyhydroxymethacrylate resins and available as strong and weak anion and cation exchangers (SP, CM, QA, DEAE). The CQA and CQK resins are available with a bead size of 10 µm and 30 µm.

On this page you’ll find a list of the available columns and resins. For sample chromatograms of these columns you can download the PDF below.
