Abstract
A method for generating high purity acid or base in an aqueous stream for use in analysis. For generating a base for anion chromatography, the aqueous stream is directed through a cation exchange bed having strongly acid first and weakly acidic second portions. An electrical potential is applied to the bed. Cations on the bed electromigrate into the aqueous stream while hydroxide ions are electrolytically generated to form a base-containing eluent. Analytes to be detected and the generated eluent flow through a detector.
