Abstract
Ion exchange stationary phases are prepared with diprimary diamines for applications such as separating samples that contain polyvalent anions. The ion exchange stationary phase includes a series of condensation polymer reaction products bound to a substrate. The condensation polymer products are formed with diprimary diamines and polyepoxide compounds. The ion exchange stationary phases described herein are capable of separating monovalent and highly polyvalent anions relatively quickly with relatively low eluent concentrations in one chromatographic run.
