Title:

ELECTRODIALYSIS SUPPRESSOR FOR ION CHROMATOGRAPHY

Document Type and Number:

WIPO Patent Application WO/2005/046832

Kind Code:

A1

Abstract:

The invention relates to an ion chromatography analysis, more specifically to devices for reducing a background signal during a conductometric ion determination by an ion chromatography method. The inventive electrodialysis suppressor for the ion chromatography comprises an eluent channel which is bound on two side thereof by flat ion-exchange membranes and filled with an ion-exchange material embodied in the form of a net or resin, two regenerant solution channels which are filled with nets and formed by the ion-exchange membrane surfaces which are external with respect to the eluent channel and by inert plates. Said suppressor also comprises two electrodes which are arranged in chambers filled with said regenerant solution. Said invention is characterised in that each electrode is embodied in the form of an electroconductive layer applied to the membrane surface which is oriented towards the chamber containing the regenerant solution.
