Abstract

A hydroxymethyl methacrylate-based anion exchanger with quaternary amine functional groups is shown to have a proper selectivity for the separation of common inorganic anions on chemically suppressed ion chromatography systems. Its performance is comparable to the agglomerated pellicular-based anion exchangers commonly used for this purpose. The applications of this new anion exchanger as an alternative stationary phase for chemically suppressed ion chromatography are featured with separations of some simple inorganic and organic anions using both isocratic and gradient elution techniques.
