Book excerpt: Analytical Pyrolysis presents the Proceedings of the Third International Symposium on Analytical Pyrolysis, held in Amsterdam on September 7-9, 1976. It looks at newly emergent techniques in analytical pyrolysis, including pyrolysis mass spectrometry, gas chromatography, thin-layer chromatography, and pyrolysis-gas liquid chromatography. The book also covers topics ranging from automation and microbiology to forensic science and pharmacology, reproducibility and specificity, biochemistry, laser-induced pyrolysis, pyrolytic reaction mechanisms, and polymers. Comprised of 50 chapters, this book begins with a discussion of automatic analysis of tire rubber blends using computer-linked pyrolysis gas chromatography, thermal procedures in coupling with thin-layer chromatography, the role of pyrolysis-gas liquid chromatography in biomedical studies, and the identification of microorganisms by pyrolysis gas-liquid chromatography. It then examines forensic applications of analytical pyrolysis techniques, structure and degradation behavior of synthetic polymers using pyrolysis in combination with field ion mass spectrometry, determination of polysaccharides in fulvic acids by pyrolysis gas chromatography, and application of Curie-point pyrolysis mass spectrometry in fungal taxonomy. The reader is also introduced to pyrolysis mass spectrometry of model compounds labeled with stable isotopes, the use of pyrolysis/gas chromatography to determine the quality of porous polymers of styrene cross-linked with divinyl benzene, and application of pyrohydrolysis for a rapid and accurate determination of halides in silicate rocks and minerals. This volume will benefit students, researchers, chemists, and scientists working in the field of analytical pyrolysis.

Available in PDF, EPUB and Kindle. Book excerpt: Analytical pyrolysis allows scientists to use routine laboratory instrumentation for analyzing complex, opaque, or insoluble samples more effectively than other analytical techniques alone. Analytical Pyrolysis Handbook, Third Edition is a practical guide to the application of pyrolysis techniques to various samples and sample types for a diversity of fields including microbiology, forensic science, industrial research, and environmental analysis. The much-anticipated third edition incorporates recent technological advances that increase the technique’s sensitivity to trace elements, improve its reproducibility, and expand its applicability. The book reviews the types of instrumentation available to perform pyrolysis and offers guidance for interfacing instruments and integrating other analytical techniques, including gas chromatography and mass spectrometry. Fully updated with new sample pyrograms, figures, references, and real-world examples, this edition also highlights new areas of application including cultural materials, forensic analysis, and environmental studies. This book illustrates how the latest advances make pyrolysis a practical, cost-effective, reliable, and flexible alternative for increasingly complex sample analyses. Analytical Pyrolysis Handbook, Third Edition is an essential, one-stop guide for determining if pyrolysis meets application-specific needs as well as performing pyrolysis and handling the data obtained.
Download or read book Using Gas Chromatography Mass Spectrometry for the Detection of Polycyclic Aromatic Hydrocarbons and Nitropolycyclic Aromatic Hydrocarbons in Soil and Diesel Particulate Matter written by Mario J. Mena (Jr) and published by . This book was released on 2018 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particular matter (PM, e.g. soot, dust etc.) of a certain size is known to be hazardous to human health. These particles are small enough to travel through our respiratory system and induce respiratory illness by introducing foreign bodies and toxic chemicals to our systems. For instance, benzo(a)pyrene (BaP), is an example of a polycyclic aromatic hydrocarbon (PAH) frequently found in or on PM known to have carcinogenic and mutagenic effects. Polycyclic aromatic hydrocarbons are by-products of incomplete combustion such as vehicle emissions. Thus, when PM are airborne, they can interact with semi-volatile molecules such as PAH. In turn, the newly coupled system may penetrate our respiratory system. In addition to PAH, nitro polycyclic aromatic hydrocarbons (NPAHs, i.e. 1-nitro-pyrene) are being recognized by the International Agency for Research on Cancer as a Group 2a compound (probably carcinogenic to humans). This study aims to identify chemical signatures of forest fire and automobile emissions using ratios of PAH and its oxidants, including nitro-PAH, in a variety of media (e.g. soil, soot, PM). Nitro-PAH (NPAHs) are usually found in/on course/fine particular matter at concentrations on the order of 2ng/mL to 200ng/mL (Heidelore et al. 1991, Eiguren-Fernandez et al 2004). Therefore, a very sensitive technique is needed to detect NPAHs in various matrices representative of those found in the environment. This study will use the following PAH ratios to differentiate sources of incomplete combustion: B[a]P to (B[a]P+chrysene; pyrene to B[a]P; fluoranthrene to pyrene; and fluoranthrene to (fluoranthrene+pyrene). As for the NPAH:PAH ratios, the following will be used: 1-nitro-pyrene to pyrene; 6-nitro-chyresene to chrysene; and 6-nitro-benzo[a]pyrene to benzo[a]pyrene. Extractions of PAH will be performed using the accelerated solvent extraction technique. Gas chromatography-mass spectroscopy will be used to identify and quantify analytes. The results of this study may be used to inform citizens, city planners and lawmakers about the impacts of high-traffic events on human health.
Download or read book Mass Spectrometry of Priority Pollutants written by Brian Middleditch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the list of organic priority pollutants was first published, many mass spec troscopists went scrambling to their reference books. GC-MS was mandated for the analysis of 114 compounds, yet the spectra of many of them, if they had been recorded at all, were scattered throughout the literature. Moreover, it soon became apparent that, even if a sufficient number of instruments could be made available to undertake the task of monitoring 114 substances in the effluents of 21 categories of industry, the personnel could not be trained to perform the analyses and interpret the results. The solution to this problem has been the development of highly automated mass spectrometers which can be operated by personnel without the traditional research training. This book is for the new breed of mass spectroscopist who is not interested in the esoteric details of mass spectral fragmentation, but who merely wishes to identify specific pollutants in effluents. Our inclusion of com prehensive lists of synonyms and bibliographic data should make the book of even greater value to the reader who is not too familiar with the idiosyncrasies of chemical nomenclature and the scientific literature. The experienced mass spectroscopist should also benefit from having all of the data collected together in one volume. This is a book to be used, rather than deposited in a library distant from the laboratory: we would hope that it will fmd a place on top of every mass spectrometer used for the analysis of priority pollutants.

This book was released on 2016 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography mass spectrometry (LC-MS) are powerful analytical techniques that combine the separation power in a stationary phase with the detection power of mass spectrometry. GCMS and LC-MS have gained dominant positions in identifying and quantifying different analyte species due to their high selectivity, high sensitivity, and high reproducibility. My research utilizes the analytical power of LC-MS and GC-MS to address two environmental issues: 1) Identification of biodegradation products of the ionic liquid 1- butyl-3-methylimidazolium chloride (BMIMCl) by an activated sludge microbial community using LC-MS and 2) identification and quantification of polycyclic aromatic hydrocarbons (PAHs) in the Kalamazoo River oil spill using GC-MS. Three major metabolites from BMIMCl biodegradation were identified, and their structures were confirmed using MS/MS and 1H-NMR techniques. Many PAHs were identified, and their concentrations were quantified in the Kalamazoo River oil spill area using GC-MS.
