Title:
ELECTROLYTIC SUPPRESSOR AND SEPARATE ELUENT GENERATOR COMBINATION
Document Type and Number:
WIPO Patent Application WO2002004940
Kind Code:
A9
Abstract:
A combination electrolytic suppressor and separate eluent generator and method. The suppressor includes a chromatography effluent flow channel, an ion receiving flow channel, and a first suppressor ion exchange barrier therebetween permeable to electrolyte ions but not liquid flow. The effluent from the chromatography effluent compartment flows through the detector, the ion receiving channel, and to an eluent generator. The generator includes a first generator electrode in a first generator electrode chamber, an electrolyte ion reservoir, a first charged generator barrier separating the first eluent generator electrode chamber from the electrolyte ion reservoir, preventing liquid flow but permitting transport of said electrolyte ions, and a second generator electrode on the opposite side of the first generator barrier from the first generator electrode. Fluid flows from the ion receiving flow channel past the second generator electrode. Acid or base electrolytically generated in the first generator electrode chamber flows as an eluent stream to the chromatographic separator.
