Abstract
Apparatus for analysis of ionic species in an aqueous liquid stream comprising: (a) a chromatographic separator (10) including medium for separating said ionic species and having an inlet and outlet (b) a source of an aqueous eluent solution comprising electrolyte in fluid communication with said chromatographic separator; (c) a membrane suppressor (12) comprising a chromatography affluent flow channel separated by an ion exchange membrane from a regenerant flow channel having an inlet and an outlet; (d) a container (26) including an inlet and an outlet, said container outlet being in fluid communication with said regenerant flow channel; (e) a regenerant liquid reservoir (28) in said container of a different chemical composition than said chromatography affluent; (f) a detector (16) for detecting ionic species in fluid communication with said chromatography effluent flow channel; and (g) a recycle conduit (30) for the flow of effluent from said detector to said container inlet.
