Abstract
A method and apparatus for ion analysis by ion chromatography uses periodic electrolytic regeneration of a packed bed suppressor. First and second sets of columns, suppressors and detectors connected in series are linked by appropriate valving so that the effluent from the second suppressor can be passed to the first suppressor to be used in the electrolytic regeneration of the first suppressor after detection of analyte in the second detector.
