Benzoic acid is introduced as an eluent and is compared with benzoate salt eluents. Detector response to sample ions in single-column ion chromatogrphy is compared with dual-column (suppressed) ion chromatography. Benzoic acid has a higher background conductance; however, samples separated with benzoate salt eluents. Comparable sample peak areas are found with suppressor column treated benzoate eluents and benzoic acid eluents. Equations are described which predict detector response for a variety of conditions.
