ABSTRACT
At present, ion chromatography has a dominant position among the separation methods used for the analysis of inorganic anions [1-4]. However, when the separation efficiencies typically achieved by ion chromatography are compared to characterising capillary zone electrophoresis for analysis of a group of analytes, it is apparent that the latter technique has advantages. As the effective mobilities of inorganic anions are sufficiently due to differences in their ionic mobilities they can be influenced in a desired way via appropriately selecting (differences in pK a values) and/or via the use of suitable additives [5], the selectivity factors [6] are also favourable leading to rapid resolutions of the analytes by capillary zone electrophoresis.
