Strong Acid Cation Exchange Resin vs. Weak Acid Cation Exchange ... interstate officeWeband out of the polymer. Ion exchange resins have been classified based on the charge on the exchangeable counterion (cation exchanger or anion exchanger) and the ionic strength of the bound ion (strong exchanger or weak exchanger). Thus, there are four primary types of ion ex-change resins: 1. Strong cation exchange resins, containing sulfonic acid interstate office partitions incA "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.
