The separation of nine mono- and divalent cations of interest in explosive residue analysis was achieved using ion chromatography with eluent and conductivity detection.
Abstract
Data were collected on cation types found in various explosive residues, including black powder, smokeless powder, and ammonium nitrate explosives. The conductivity detector, in combination with the ion chromatography column, allowed the successful resolution of nine major cations found in postblast explosive residues. The authors conclude that the ability to precisely identify cation composition in explosive residues is an important aid in determining the chemical composition of explosive devices and that their technique can be useful in further research and data collection on the postblast composition of explosives. 14 references, 1 table, and 5 figures
