This book describes nerve agents and vesicants, their decomposition and their degradation products' chemistry as well as their toxicity including a list of detection techniques of nerve agents and their degradation products. This book will present their history, toxicity, comparison between different sample preparation methods, separation techniques, and detection methods all together in a short, easy to read book, tied together by a single group doing the writing and the editing to assure smooth transition from chapter to chapter, with sufficient Tables and literature references for the reader who looks to further detail.The text will illustrate the pluses and minuses of the various techniques with sufficient references for the reader to obtain extensive detail.
Over the past several years Defence Research Establishment Suffield (DRES) developed LC-ESI-MS methods for the analysis of a variety of samples of chemical defence interest. These samples included hydrolysed munitions grade mustard, degraded 0-ethyl S-2-(DIISOPROPYLAMINO)ETHYL methylphosphonothiolate (VX), snow contaminated with sarin (GB), soil contaminated with sarin (GB) and soman (GD), munitions grade tabun (GA), failed synthetic products and synthetic standards. During these investigations DRES acquired ESI-MS data for sixty chemical warfare agents, degradation products and related compounds. Data were obtained with a resolution of 5000 (50% valley definition) in the continuum mode at several sampling cone voltages. At lower sampling cone voltages the mass spectra were dominated by protonated, sodiated and protonated acetonitrile adducts and/or their dimers that could be used to confirm the molecular mass of each compound. Structural information was obtained by inducing product ion formation in the ESI interface at higher sampling cone voltages. Representative data obtained at both a lower and higher sampling cone voltage were selected for entry into the DRES ESI-MS Database as part of a collaboration between Canada (DRES) and The Netherlands (TNO Prins Maurits Laboratory).
Gas Chromatography/Mass Spectrometry (GC/MS) analysis of many chemical agents, particularly the V series, under standard Electron Ionization (EI) conditions often produces extensive fragmentation making identification difficult Milder Chemical Ionization (CI), typically using methane, isobutane, or ammonia as reagent gases, is commonly used to provide molecular weight and structure confirmation. In this study, acetonitrile was used as a liquid CI reagent for detection of HD, VX, and related compounds using an ion trap detector. The protonated molecular ion was observed as the dominant ion and base peak for HD, VX, GA, 1,4-dithiane, 2-diisopropylaminoethanol, and the trimethylsilyl derivatives of methylphosphonic acid and isopropyl methylphosphonic acid. Acetonitrile was not effective for GB. The use of liquid reagents offers logistical advantages for field analysis by being easier to transport and safer to use than gas cylinders. The major drawback of acetonitrile is that it requires significant equilibration time which limits versatility if rapid switching between EI and CI is required.
A concise but comprehensive annual survey of a vast field of study enabling the reader to rapidly keep abreast of the latest developments in this specialist area.
A survey of the key issues related to chemical and biological warfare discusses known chemical and biological agents and how they are weaponized, the roles they have played in history, and the actual risk of their being used today.
