Describes the procedures for collection of samples, sample preparation, and analysis of CWC-related chemicals. It deals with analytical procedures that can be followed in well-equipped off-site laboratories (designated laboratories), as well as the on-site analytical procedures that the OPCW inspectors use in sample collection and preliminary analysis of the samples in field conditions. A one-of-a-kind, highly topical handbook for every expert in the chemical weapons field Outlines the methods for analysing chemical weapons both on and off site Authored by international experts in the field from top laboratories in both government and academic institutions
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).
This textbook is the first to present a systematic introduction to chemical analysis of pharmaceutical raw materials, finished pharmaceutical products, and of drugs in biological fluids, which are carried out in pharmaceutical laboratories worldwide. In addition, this textbook teaches the fundamentals of all the major analytical techniques used in the pharmaceutical laboratory, and teaches the international pharmacopoeias and guidelines of importance for the field. It is primarily intended for the pharmacy student, to teach the requirements in “analytical chemistry” for the 5 years pharmacy curriculum, but the textbook is also intended for analytical chemists moving into the field of pharmaceutical analysis. Addresses the basic concepts, then establishes the foundations for the common analytical methods that are currently used in the quantitative and qualitative chemical analysis of pharmaceutical drugs Provides an understanding of common analytical techniques used in all areas of pharmaceutical development Suitable for a foundation course in chemical and pharmaceutical sciences Aimed at undergraduate students of degrees in Pharmaceutical Science/Chemistry Analytical Science/Chemistry, Forensic analysis Includes many illustrative examples
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.
