Ion chromatography apparatus and method for removing gas prior to sample detection

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...

Beschreibung
Zusammenfassung:	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.
