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 (14) after chromatographic separation. For anion analysis, the method includes: (a) flowing an aqueous feed stream through the first bed section (14) while applying an electrical potential, (b) flowing a liquid sample stream containing anions to be detected and the eluent through a chromatographic separator portion (14) of said first bed section, to separate said anions to be detected, (c) flowing said aqueous separated anion stream through said second bed section (16) free of anionic material and including exchangeable hydronium ions, while applying an electrical potential, and (d) detecting the separated anions in said suppressor effluent.
