Book Synopsis Gas Chromatography Coupled with Ion Trap Mass Spectrometry (GC-MS and GC-MS-MS) - for Arson Debris Analysis by : Betty-Jane De Vos
Download or read book Gas Chromatography Coupled with Ion Trap Mass Spectrometry (GC-MS and GC-MS-MS) - for Arson Debris Analysis written by Betty-Jane De Vos and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas chromatography - mass spectrometry (GC-MS) is an established instrumental technique used for the analysis of fire debris for accelerant detection. However, matrix problems, such as pyrolysis product interference, are still encountered. These interferences often lead to inconclusive interpretation of the chromatographic results. This study describes methods for analysing arson accelerants using gas chromatography coupled with ion trap mass spectrometry. The latter technique lends itself to both conventional (GC-MS) as well as tandem mass spectrometry (GC-MS-MS). Since petrol (gasoline) is one of the more common distillate blends used by arsonists, especially in South Africa, the identification of petrol in fire debris samples was investigated. In order to overcome pyrolysis product interference and improve detection selectivity of the aromatic hydrocarbons in petrol residues, tandem mass spectrometry was used in combination with capillary gas chromatography. The added parameter of the third dimension of selectivity proved to be superior to conventional GC-MS in obtaining characteristic aromatic hydrocarbon profiles for petrol without interference from pyrolysis artefacts.

Book Synopsis A Survey on the Interpretive GC/MS Analysis of Fire Debris by : Anthony Thomas Parks
Download or read book A Survey on the Interpretive GC/MS Analysis of Fire Debris written by Anthony Thomas Parks and published by . This book was released on 2018 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practice of arson analysis in a forensic science laboratory is based upon detecting the presence of ignitable liquids. If an ignitable liquid is present, it is suggestive of arson; if no ignitable liquid is found an arson claim is more difficult to assert. Ignitable liquids are detected using gas chromatography coupled with mass spectrometry. Instrumental results from a GC/MS can display components of an ignitable liquid but an analyst needs to make the final decision. Even with correct instrumentation and suggested guidelines, ignitable liquid analysis can be subjective and based upon the analysts' education and experience. To better understand the interpretive practices of the fire debris analysis community, a survey consisting of reference samples, mixture standards, and multiple unknowns was created in consultation with the Los Angeles Police Department Arson Unit. The samples consisted of different substrates with varying classes and volumes of ignitable liquid. They were created using a destructive distillation method first developed by the State of Florida Bureau of Forensic Fire and Explosives Analysis. Extraction of the samples was completed using a carbon strip to perform passive headspace absorption following the ASTM E 1412 method. The samples were analyzed with a GC/MS following National Commission on Forensic Science parameters. To maintain confidentiality, participant responses are stripped of identifiers and the results of the survey, details about the procedure, and discussions will be presented.
Book Synopsis Accelerant Identification in Fire Debris by Gas Chromatography/Mass Spectrometry Techniques by : RL. Kelly

This book was released on 1984 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire debris suspected of being involved in arson fires or fire bombings is extracted and analyzed for the presence of flammable and combustible liquids by gas chromatography/mass spectrometry (GC/MS) Pentane extractions of debris or neat liquids are examined by GC/MS and the resulting GC profiles and reconstructed ion chromatograms (RICs) are used to characterize and identify accelerants. This technique, using selected ions to generate profile charts during data processing, enables the differentiation and identification of a variety of petroleum products and solvents used in arson fires.
Book Synopsis Pyrolysis-gas Chromatography: Mass Spectrometry Of Polymeric Materials by : Peter Kusch
Download or read book Pyrolysis-gas Chromatography: Mass Spectrometry Of Polymeric Materials written by Peter Kusch and published by World Scientific. This book was released on 2018-10-08 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The methodology of analytical pyrolysis-GC/MS has been known for several years, but is seldom used in research laboratories and process control in the chemical industry. This is due to the relative difficulty of interpreting the identified pyrolysis products as well as the variety of them. This book contains full identification of several classes of polymers/copolymers and biopolymers that can be very helpful to the user. In addition, the practical applications can encourage analytical chemists and engineers to use the techniques explored in this volume.The structure and the functions of various types of pyrolyzers and the results of the pyrolysis-gas chromatographic-mass spectrometric identification of synthetic polymers/copolymers and biopolymers at 700°C are described. Practical applications of these techniques are also included, detailing the analysis of microplastics, failure analysis in the automotive industry and solutions for technological problems.
