Stacking in CE for Analysis of Bromate Flour Additive.

In this paper we report a simple and effective on-line sample-stacking method in capillary electrophoresis for analysis of bromate ion. The detection limit is 10.9 ng mL⁻¹. Direct injection is performed after a simple extraction procedure. It is possible to detect 2.18 mg kg⁻¹ bromate ion in flour by use of this technique. [ABSTRACT FROM AUTHOR]
