Abstract
Using both UV-Vis and conductivity detectors, the effects of high concentration of chloride on the determination of trace anions were studied on three different analytical columns by ion chromatography. The variations of retention behavior of these anions were caused by self-elution effect and on-column eluent change in the presence of high concentration of chloride. As the chloride concentration increased, linear ranges of the other anions became narrow. The anions separated on the column, which had higher capacity and had wider linear ranges. When their peaks overlapped with chloride, the deviations of weak acid anions were caused by anion-proton interactions within the suppressor. However, the other weak acid anions, which could not overlap with chloride and the strong acids anions, were not affected. In this paper, accurately quantitative analysis methods and their linear ranges were determined.
