Abstract

A method of chromatographically separating ionic species in an aqueous electrolyte-containing eluent to form an effluent, suppressing the effluent, detecting the suppressed effluent and passing the detected effluent to a regenerant reservoir, thereby displacing the regenerant to flow to the suppressor, wherein the regenerant and effluent are of different chemical compositions.
