This document describes a method for rapidly determining the identity of anionic toxins, such as cyanide and arsenite, in adulterated foods and beverages. The technique uses capillary electrophoresis (CE) with indirect UV detection to achieve results within 15 minutes with minimal sample preparation.
Cyanide, arsenite, arsenate, selenate, azide, and other anions can be detected within 15 minutes.
The method requires only minimal sample preparation.
The assay was linear over the range 10-100 ppm.
