Summary
The presence of high concentrations of chloride in urine and seawater samples interferes with the separation of arsenic species by ion chromatography; single peaks may be split into two or more discrete peaks, as a result of the large differences in the ionic strengths of the mobile and injection solvents. A simple model is proposed to explain this phenomenon.
