Low-capacity cation-exchange stationary phases for ion chromatography were prepared by coating a vinyl-modified silica gel with polystyrene in a reproducible way. Ion-exchange groups were formed by sulfonation of the polystyrene-coated silica gels. These strongly acid cation-exchangers were used for
