Use of aliphatic thiols for on-site derivatization and gas chromatographic identification of Adamsite

The report describes the development of methods for rapid and simple identification Adamsite in mobile laboratory conditions using a field gas chromatograph coupled with mass spectrometer. is chemical warfare agent unique properties that cannot be analysed without conversion to volatile derivative. Derivatization procedures 5 aliphatic thiols (ethanethiol, 1-propanethiol, 2-propanethiol, 1-butanethiol 1-hexanethiol) were developed compared. retention characteristics derivatization products, peak formation unwanted artifacts chromatograms monitored. influence reaction media time dependence also objects interest. Other investigated parameters optimal temperature volume agent. Mass spectra newly created substances are not yet included weapons related databases recorded. With reagents (1-butanethiol 1-hexanethiol), calibration analyte determination subsequently developed, verified during test selected environmental urban matrices.
