Chiarotti, M. published the artcileThin-layer and high-performance liquid chromatographic analyses of organic gunshot residues, Quality Control of 1821-27-8, the publication is Nippon Hoigaku Zasshi (1987), 41(2), 65-70, database is CAplus and MEDLINE.
TLC, normal HPLC, and reversed-phase HPLC were investigated for identification of organic unburnt gunshot residues. Reversed-phase HPLC shows high sensitivity (1-6 ng) for diphenylamine and nitroglycerin (UV detection 280 nm), and it is proposed as a promising tool in forensic studies. Exptl. conditions are given in extensive details.
