Abstract
Anion analyses can provide important leads in the forensic investigation of bombings and poisonings. The determination of these negative ions by ion chromatography or capillary electrophoresis provides information on the chemical species of the anions. In addition, these techniques provide a means for the separation of complex mixtures. Separating mixtures and providing speciation are two major advantages of ion chromatography and capillary electrophoresis over elemental analysis. The forensic application of analytical methods for anions found in explosives and poisons is discussed, and relevant examples are presented in this article.
