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

A method of detecting analyte ions by continuous electrochemically suppressed ion chromatography comprising: (a) flowing analyte ions in an aqueous mobile phase comprising electrolyte through an analytical column separating means to form an aqueous chromatography effluent comprising separated analyte ions and electrolyte; (b) flowing the aqueous chromatography effluent through a suppressor means for splitting the chromatography effluent into a first chromatography effluent flow stream and a second chromatography effluent flow stream; (c) applying an electrical potential in the suppressor means such that electrolyte is electrochemically driven into the first chromatography effluent stream and away from the second chromatography effluent flow stream; (d) flowing the second chromatography effluent flow stream out of the suppressor means; (e) detecting the analyte ions in the second chromatography effluent flow stream.
