Anion-exchange columns designed for use with ion chromatography systems and methods, available in a range of dimensions and formats. Use hydroxide-selective columns for inorganic anions, oxyhalides, organic acids, haloacetic acids, or multivalent anions in complex matrices. Alternatively, choose columns for use with carbonate eluents for well-characterized isocratic separations.
