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.

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.

This book was released on 2010-11-05 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threat of biological and chemical terrorism has driven the demand for timely techniques that can quickly detect the agent or agents used in an attack. The detection and/or prevention of these potential security threats provide significant scientific and technical challenges due to the combination of possible agents and modes of delivery available. This book will present a thorough look at the importance and technological challenges of mass spectrometry (MS) for the detection & identification of biological and chemical threats. This new contribution’s general aims are to draw the attention of recognized practitioners, experts and graduate students trying to grasp the latest MS developments in the cutting-edge fields of MS-biodefense technologies for the rapid/early/specific sensitive threat detection of pathogens, viruses, explosives, mycotoxins, chemical agents, and biological markers of xenobiotic chemicals.

This book was released on 2009 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: A "dip and shoot" analytical method was developed for the rapid sampling and desorption electrospray ionization mass spectrometric (DESI-MS) analysis of chemical warfare agents and their hydrolysis products in liquid samples. Sampling was performed by simply dipping fused silica, stainless steel or SPME tips into the organic or aqueous samples. Replicate analyses were completed within several minutes under ambient conditions with no sample pre-treatment, resulting in a significant increase in sample throughput over conventional solid phase microextraction (SPME) sampling and DESI-MS analysis or liquid chromatographic electrospray ionization mass spectrometric (LC-ESI-MS) analysis. The developed sample handling and analysis method was applied to the determination of chemical warfare agent content in samples containing unknown chemical and/or biological warfare agents. Ottawa sand was spiked with mustard, extracted with water and autoclaved to ensure sterility. Mustard was completely hydrolysed during the extraction/autoclave step and thiodiglycol was identified by DESI-MS, with analyses generally being completed within one minute using the "dip and shoot" method developed for the rapid analysis of liquid samples.
