Abstract

Apparatus for 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.
