Abstract (en)
[origin: WO9418555A1] Apparatus and method for ion chromatography having a chromatography column (10) followed by a suppressor (11) for converting the eluent electrolyte to weakly ionized form and converting analyte ions to acid or base form. First detection of analyte ions occurs in a first conductivity detector (12) followed by conversion of the analyte ions in acid or base form to salt form in a salt converter and subsequent detection in a second conductivity detector (32). Comparison of signals from the two detectors (12, 32) provides additional information about the analytes.
