A new method has been developed to allow the determination of the chlorate, chloride and perchlorate anions in inorganic explosive residues to bemadeusing isotachophoresis (ITP). To enable a good separation of these species to be achieved the method involves the use of two complexing agents. Indium(III) is used to allow the determination of chloride whilst using nitrate as the leading ion and -cyclodextrin is used to allow the separation of chlorate and perchlorate. Separations were carried out using a miniaturised poly(methyl methacrylate) (PMMA) separation device. The method was applied to analysing both model samples and actual inorganic explosive containing residue samples. Successful determinations of these samples were achieved with no interference from other anions typically found in inorganic explosive residues. Limits of detection (LOD) for the species of interestwere calculated to be 0.80mgl−1 for chloride, 1.75mgl−1 for chlorate and 1.40mgl−1 for perchlorate.
