This book was released on 2006 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ratification of the Chemical Weapons Convention by more than 165 States Parties has reduced the risk of chemical warfare agent use, but there still remains a concern that other parties may make use of these weapons against civilian or military targets. Concerns within the defense and homeland security communities over possible terrorist use as well as the requirements for a verifiable Chemical Weapons Convention have driven the development of analytical methods such as liquid chromatography-mass spectrometry (LC-MS) for the detection and identification of chemical warfare agents. This paper provides a general overview of chemical warfare agents and analytical methods for their analysis, a focused review of LC-MS applications, a summary of in-house LC-MS methods developed at DRDC Suffield, and a comprehensive bibliography of analytical open literature papers dealing with chemical warfare agent detection and identification. The review sections provide the homeland security and defense communities with an overview of chemical warfare agents and analytical methods for their determination. Researchers interested in developing new methods for chemical warfare agents may use the reviewed material to quickly ascertain the state of development of analytical methods, in particular LC-MS methods, for chemical warfare agents. The reviewed materials will be used for reference purposes during the development of high field asymmetric waveform ion mobility spectrometry (FAIMS) mass spectrometry, a new analytical technique with the potential to rapidly separate and identify chemical warfare agents. The report concludes with 67 references. Appendix A is a 454-item bibliography of open literature analytical methods for the detection and identification of chemical warfare agents, their degradation products, and related compounds. Paper copies of each paper are held at DRDC Suffield and this comprehensive database of methods continues to be updated regularly using Procite software.
Book Synopsis Application of Solid Phase Microextraction with Gas Chromatography-Mass Spectrometry as a Rapid, Reliable, and Safe Method for Field Sampling and Analysis of Chemical Warfare Agent Precursors by : Douglas K. Parrish
Download or read book Application of Solid Phase Microextraction with Gas Chromatography-Mass Spectrometry as a Rapid, Reliable, and Safe Method for Field Sampling and Analysis of Chemical Warfare Agent Precursors written by Douglas K. Parrish and published by . This book was released on 2005 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid phase microextraction was combined with gas chromatography-mass spectrometry (SPME-GC-MS) for detection of hydrogen cyanide (HCN) in the headspace above deionized (DI) water samples, with linear results that were sensitive to below Department of Defense short-term drinking water standards. HCN and several common volatile organic contaminants were also detected in 3 water types in a laboratory and field setting. The method provides an advantage over the standard drinking water detection methods for HCN as it can also simultaneously detect common low molecular weight hydrocarbons. Linear results were achieved for the detection of diisopropylamine (DIPA) by SPME-GC-MS in soil from 0.72 - 3584.5 micrograms DIPA/g soil and in DI water from 0.018 - 17.9 microgram/milliliter. The methods were successfully field tested with common hydrocarbon contaminants in 3 common agricultural soil types and 3 water types. In particular, this methodology would be useful for investigation of a suspected VX nerve agent production facility. Solid phase dynamic extraction (SPDE) was compared to passive SPME for vapor sampling of DIPA and dimethyl methylphosphonate (DMMP) with analysis by fast GC-MS. Equilibrium sampling by SPDE for DIPA and DMMP vapor provided linear results at lower concentrations and gave larger extracted ion peak areas than comparable SPME sampling. This unique application has shown great potential for further laboratory and field use, both for health risk assessment and initial chemical detection employment.

Hancock and published by . This book was released on 1999 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sample preparation and identification techniques for chemical warfare and mid-spectrum agents were surveyed as part of Canada's contribution to a joint NATO project to create a NATO Handbook on the sampling and identification of biological and chemical agents. Sample preparation techniques such as solid phase extraction, supercritical fluid extraction and derivatization were reviewed with respect to their applicability to chemical warfare and mid-spectrum agents. Identification techniques including; gas chromatography, liquid chromatography, mass spectrometry, Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy were examined in light of the need to confirm the identity of these agents in the presence of complex background matrices.
Book Synopsis Identification of Soil Organics Using a Gas Chromatographic Mass Spectrometric Method by : William F. O'Reilly
Download or read book Identification of Soil Organics Using a Gas Chromatographic Mass Spectrometric Method written by William F. O'Reilly and published by . This book was released on 1974 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a study on the role of natural organics in determining the physical properties of soils, the use of combined gas chromatographic/mass spectrometric methods for identification of the more volatile organic chemicals in soils were explored. Soil was first treated at 100, 150, and 200C to select the optimum temperature where minimum pyrolysis of soil organic matter occurred. The vapors from three soils heated in a closed system at 150C were then analyzed. Subsequent refinement in technique involved collection of vapor from the three soils maintained at 150C using a constant flow sample holder/inlet system. About 50 organic compounds were identified. While application of this approach is restricted to the volatile compounds in the lower molecular weight range, conditions of analysis are thought to be suitable for identification of compounds originally present as opposed to pyrolysis products of soil organic matter.

Download or read book Sampling Handling and Analysis Method for Chemical Warfare Agents in Soils Contaminated With Chemical And/or Biological Warfare Agents written by and published by . This book was released on 2003 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sample handling and analysis method was developed for the identification of chemical warfare agents (as intact compounds or as their hydrolysis products) in samples suspected to contain either chemical or biological warfare agent contamination. The method, based on aqueous extraction, autoclaving of the aqueous extract and LC-ESI-MS analysis was evaluated using three soil samples spiked at the 80 microgram/g level with triethyl phosphate, isopropyl methylphosphonic acid or thiodiglycol. All three compounds were readily extracted and identified following LC-ESI-MS, with triethyl phosphate undergoing some hydrolysis during the autoclaving procedure. This sample handling and analysis method for soil (or other) samples will form a cornerstone of the chemical/biological warfare agent identification strategy being developed at DRDC Suffield to meet National commitments.

Download or read book Analysis of Chemical Warfare Agents by GC-MS: First Chemical Cluster CRTI Training Exercise written by and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemical Cluster, one of three clusters created by the Chemical, biological, radiological and nuclear Research and Technology Initiative (CRTI), was established to help Canada prepare for possible terrorist events. This working group, made up of representatives from Canadian government departments, has identified a number of chemicals of concern and assigned laboratories with appropriate expertise to provide the analytical support necessary to confirm these compounds in suspect samples. The Royal Canadian Mounted Police (RCMP), in its lead forensics role, will attempt to tentatively identify the chemical(s) of concern and pass on the samples to the responsible laboratory within the Chemical Cluster. Samples containing large amounts of relatively pure chemical warfare agents should trigger a response with one the chemical monitoring devices (e.g., Chemical Agent Monitor) used by the RCMP to triage samples. Defence R & D Canada - Suffield (DRDC Suffield) has been tasked to analyse samples suspected to contain chemical warfare agents for the Chemical Cluster and would receive this type of suspect sample. There remains a possibility that samples with a lower level of chemical warfare agent contamination might inadvertently find their way into a laboratory tasked with another type of analysis. To manage this possibility, the laboratories receiving these types of samples should have an analytical screening capability to allow for the tentative identification of chemical warfare agents in samples and sample extracts. This report summarizes the chemical warfare agent training course in sample preparation and analysis by gas chromatography-mass spectrometry (GC-MS) given by DRDC Suffield to other Chemical Cluster laboratories.

Part 2: Solid Phase Microextraction written by Van and published by . This book was released on 1998 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a collaborative study of the Military Institute of Chemistry and Radiometry (WICHIR), Poland, and TNO Prins Maurits Laboratory (TNO-PML), The Netherlands, explorative investigations were conducted on the use of a relatively new method for the extraction of water samples, solid phase microextraction (SPME), in combination with gas chromatographic - mass spectrometric (GC-MS) analysis. SPME-GC-MS of the following compounds was explored: triethyl phosphate, dimethyl methylphosphonate, sarin, VX, methyldiethanolamine and thiodiglycol. The explorative investigations with SPME-GC-MS were successful for most of the above compounds. Special aspects investigated concerned derivatisation of methyldiethanolamine and thiodiglycol on the SPME fibre and extraction enhancement of VX by the addition of salt and by changing pH. SPME-GC-MS analysis of spiked water samples provides detection limits of less than 1 ng/ml (1 ppb) for sarin using selective ion monitoring, and of around 100 ng/ml (100 ppb) for triethyl phosphate, dimethyl methylphosphonate, vx, methyldiethanolamine and thiodiglycol using full mass spectrum scanning. The analysis of thiodiglycol produced inconsistent results between the collaborative laboratories, and extraction and derivatisation of this compound require more affection. In conclusion, the introduction of SPME technology provides a useful extension to the analytical chemistry methods available in both laboratories.
