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.

Download or read book High Flow Air Sampling for Field Detection Using Gas Chromatography mass Spectrometry written by Jacolin Ann Murray and published by . This book was released on 2011 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to rapidly detect and identify hazardous analytes in the field has become increasingly important. One of the most important analytical detection methods in the field is gas chromatography-mass spectrometry (GC-MS). In this work, a hand-portable GC-MS system is described that contains a miniature toroidal ion trap mass analyzer and a low thermal mass GC. The system is self-contained within the dimensions of 47 x 36 x 18 cm and weighs less than 13 kg. Because the instrument has a small footprint, it was used as the detector for an automated near-real-time permeation testing system. In permeation testing, materials that are used to make individual protective equipment such as gloves, masks, boots, and suits are exposed to hazardous analytes to determine how long the equipment can be worn safely. The system described herein could test five samples simultaneously. A multi-position valve rotated among the various sample streams and delivered time aliquots into the MS for quantitation. Current field air sampling techniques suffer from long desorption times, high pressure drops, artifact formation and water retention. These disadvantages can be avoided by concentrating the analytes in short open tubular traps containing thick films. There are several advantages to using polymer coated capillaries as traps, including fast desorption, inertness and low flow restriction. An air sampling trap was constructed utilizing open tubular traps for the concentration of semi-volatile organic compounds. The system consisted of multiple capillary traps bundled together, providing high sample flow rates. The analytes were desorbed from the multi-capillary bundle and refocused in a secondary trap. The simultaneous focusing and separation effect of a trap subjected to a negative temperature gradient was also explored. In this configuration, analytes were focused because the front of the peak was at a lower temperature than the rear of the peak and, hence, moved slower. In addition to the focusing effect, analytes with different volatilities focused at different temperatures within the gradient, allowing for separation.
