摘要：

Ion chromatography along with matrix elimination reliably determines low mu g/l levels of anionic contaminants in isopropanol. The use of ion-exchange columns that are solvent compatible makes elimination of the isopropanol sample matrix possible and allows calibration standards to be prepared in deionized water. By concentrating a large amount of sample, detection limits for chloride, sulfate, phosphate and nitrate between 0.2 and 1.0 mu g/l are achieved. The sample can be injected without sample pretreatment. The procedure is automated and yields a complete analysis in less than 1 h.
