Abstract
An apparatus for generating high purity acid or base in an aqueous stream for use in analysis. For generating a base, the aqueous stream is directed through a cation exchange bed having first strongly acidic and second weakly acidic 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.
