ABSTRACT:
A method and apparatus for generating an acid or base eluent in an aqueous stream solely from an ion exchange bed for liquid chromatography of anions or cations and for simultaneously suppressing conductivity of the eluent in the ion exchange bed after chromatographic separation. For a system in which a base is generated for the analysis of anions by ion chromatography, the method uses a bed of cation exchange material with first and second bed sections arranged in series. For anion analysis, the method includes:
