Methods for Preparing High Performance Stationary Phases for Anion-Exchange Chromatography

Abstract

The development of new high-performance anion-exchange stationary phases is one of the priority tasks of modern ion chromatography (IC). Most of the research in this field is aimed at improving the selectivity of anion exchangers and increasing the sensitivity, efficiency, and rapidity of the analysis. The selectivity of the stationary phases is largely determined by the chemistry of the adsorbent surface; therefore, it is particularly important to understand the relationship between the structure of the functional layer of the anion exchanger and its chromatographic properties. This review is devoted to methods for modifying polymer matrices in order to obtain highly efficient anion exchangers for the separation of inorganic and organic anions.
