Abstract: 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.

Abstract: An ion exchange chromatography apparatus includes a first stationary phase and a second stationary phase. The first stationary phase has at least one complexing agent functional group capable of forming a complex with at least one ion present in a sample that contains at least two ions when the sample contacts the first stationary phase. The second stationary phase is distinct from the first stationary phase and has at least one non-complexing agent functional group capable of exchanging with the ions present in the sample, other than the one complexed by the complexing agent functional group.
