Methods and devices for continuous electrochemically suppressed ion chromatography are disclosed. In preferred aspect of the invention, a chloromatography effluent comprising analyte ions and electrolyte is split into a first chromatography effluent flow stream and a second chromatography effluent flow stream. Electrolysis ions selected from the group consisting of hydronium ions and hydroxide ions are generated by the electrolysis of water. Electrolysis ions of the same charge as the electrolyte and the second chromatography effluent stream are flowed through a stationary phase thereby suppressing the electrolyte in the second chromatography effluent flow stream. The analyte ions are subsequently detected in the suppressed second chromatography effluent flow stream.

Suppressor for continuous electrochemically suppressed ion chromatography and method

Methods and devices for removing gas prior to detecting analyte ions are discolored. In one aspect of the invention, gas by-products from the suppression of the mobile phase are removed prior to detecting analyte ions at a detector. In another aspect, the amount of dissolved carbonic acid is reduced in a suppressed carbonate/bicarbonate mobile phase by removing carbon dioxide gas.
