Application of gas chromatography-mass spectrometry and gas chromatography-tandem mass spectrometry to the analysis of chemical warfare samples, found to contain residues of the nerve agent sarin, sulphur mustard and their degradation products

摘要: Samples of clothing, grave debris, soil and munition fragments, collected from the Kurdish village Birjinni, were analysed by GC-MS with selected ion monitoring (SIM) for traces chemical warfare agents their degradation products. Positive analyses confirmed, where possible, full scan mass spectra, or at low concentrations additional GC-MS-SIM analysis using ionisation, higher resolution GC-MS-SIM, GC-tandem spectrometry multiple reaction monitoring. Sulphur mustard and/or thiodiglycol detected in six samples; isopropyl methylphosphonic acid acid, hydrolysis products nerve agent sarin, different samples. Trace amounts intact sarin on a painted metal fragment associated one these The results demonstrate application GC-MS-MS techniques to unequivocal identification residues environment ranging ppb ppm (w/w). They also provide first documented environmental samples after attack.
