WebApr 14, 2024 · BioSuite Ion-Exchange HPLC Columns. Cation and anion-exchange columns (polymethacrylate based) BioSuite Ion-Exchange (IEX) Columns include four separation chemistries -- SP strong and CM weak cation-exchangers, and Q strong and DEAE weak anion-exchangers -- bonded to a pH stable (pH 2–12), methacrylic ester-based polymeric … A "strong" ion exchanger will not lose the charge on its matrix once the column is equilibrated and so a wide range of pH buffers can be used. "Weak" ion exchangers have a range of pH values in which they will maintain their charge. If the pH of the buffer used for a weak ion exchange column goes out of the capacity range of the matrix, the column will lose its charge distribution and the molecule of interest may be lost. Despite the smaller pH range of weak ion exchangers, they are …
