This book was released on 2013-11-11 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past ten years a variety of methods involving mass spectrom etry have been developed for the analysis of environmentally important compounds. Much has been accomplished in that period to solve some of the important problems in the field. Growth of this methodology and its accomplishments has reached the point where an individual scientist can no longer have an in-depth knowledge of all the areas involved. We have attempted to provide this in-depth picture to those scientists con cerned by having the important topics treated by experts in the subject matter. In order to provide all the relevant material in one volume we begin with the general topics which provide the basic background material necessary to understand the techniques discussed in the in-depth topics. These general chapters are kept brief, containing only the essentials needed by the working scientist to deal with the practical applications. References in these chapters are chosen to permit a more complete study of each chapter. The concept for this book was developed during the activities of two of the editors under a NATO travel grant. These editors gratefully acknowledge this support which made the initial planning of this book possible. The editors would like to thank the individual authors of each chap ter for their cooperation and generously giving of their time for this project.
Book Synopsis Mass Spectrometry of Priority Pollutants by : Brian Middleditch
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.
Book Synopsis The Evaluation of Environmental Contaminants Using Static Headspace Gas Chromatography Mass Spectrometry, Vacuum Ultraviolet Detection and Ionic Liquids by : Emmanuel Varona -Torres
Download or read book The Evaluation of Environmental Contaminants Using Static Headspace Gas Chromatography Mass Spectrometry, Vacuum Ultraviolet Detection and Ionic Liquids written by Emmanuel Varona -Torres and published by . This book was released on 2021 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: In analytical chemistry the term "headspace" refers to the vapor that forms above a sample (liquid or solid) in a closed container. Headspace (HS) sampling is the method to promote partition between volatile components from the sample matrix and then analyzed by gas chromatography (GC). HS is an excellent technique to introduce a"clean" vapor sample into the GC and avoids introduction of non-volatile components from the sample matrix and often used for determination of volatile organic compounds (VOCs) with minimal or no additional sample preparation. Concerns about the environmental impact of fossil fuel extraction techniques (i.e.,hydraulic fracturing and other well stimulation techniques) have risen due to its expansion in the United States and other countries. Robust atmospheric studies have attributed to the emissions of rogue greenhouse gases and VOCs to mechanical inefficiencies commonly found in the midstream production process, such as gas flaring stations, condensate tanks, and pipelines. However, the interplay between fossil fuel extraction activities and soil quality has not received much attention. Utilizing headspace gas chromatography mass spectrometry (HS-GC-MS) and an establish standard method by the Environmental Protection Agency (EPA), we present a study of soil near oil and gas production in verified emissions of volatile contaminants. The findings provide an initial indication of the interactions between atmospheric VOCs contamination events and the accumulation of those contaminants in soil where, varying soil texture was found to contribute to total amount detected. Room temperature ionic liquids (RTILs) have received significant attention in HS analysis due to their unique physiochemical properties (i.e., negligible vapor pressures, tunable thermal stabilities, tunable viscosities and wide liquid range). RTILs are salts in which ions are poorly coordinated, resulting in a liquid state at room temperature. The evaluation of RTILs as co-solvent in soil analysis, in an effort to increase sensitivity, reduce and normalized the matrix-effects associated with varying soil compositions. It was found that hydrophilic RTILs investigated, 1-ethyl-3-methylimidazolium ethylsulfate ([EMIM][ESO4]), 1-ethyl-3-methylimidazolium diethyl phosphate ([EMIM][DEP]), tris(2-hydroxyethyl)methylammonium methylsulfate ([MTEOA][MeOSO3]), reduced matrix-effect from varying soil composition thus, reducing the need to characterized and matrix-match soil textures for calibration purposes. It also reduced the analysis time and increased precision and accuracy for the quantification of VOCs in variable soil matrices relative to standard methods. Understanding the thermodynamic interactions between an analyte and the sample phase is of paramount importance when eliciting a co-solvent in HS analysis. The partition coefficient (KP) is an equilibrium constant that describes the distribution of the analyte between two phases (i.e., sample phase/ gas phase). Kp determinations by HSGC is acquired by two methods: vapor phase calibration (VPC) and phase ratio variation (PRV). Kp determinations of analytes in HS co-solvents can help guide the analyst in which to use for the analysis at hand. Here we demonstrate the ability of using a pressurized - loop HS system in conjunction with gas chromatography vacuum ultraviolet detection (HS-GC-VUV) to directly calculate the concentration of the analyte in the gas phase, by pseudo-absolute quantification (PAQ), thus allowing for quick determination of Kp and other thermodynamic properties such as enthalpy ( ∆H )and entropy (∆S ) of the system. The Kp determinations by PAQ were comparable to those obtained using theVP C method, with differences in the average values ranging

Book Synopsis Mass Spectrometry in Environmental Analysis by : Valeria Severino
Download or read book Mass Spectrometry in Environmental Analysis written by Valeria Severino and published by Arcler Press. This book was released on 2017-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of pollutants in the environment is a matter of debate since longtime. People are always more aware of the problem that is mainly related to anthropogenic compounds, and analytical methods able to detect low-amount pollutants are required. These compounds are strictly regulated by worldwide legislations aimed to develop accurate environmental risk assessment. Overall, environmental analysis is aimed to monitor and detect levels of contaminants in the water, atmosphere, soils, and other environmental conditions. One of the main challenges in this kind of analysis relies on the extreme complexity and variability of the sample to be analyzed. Compounds of interest, in fact, can be present in various matrices deeply variable according to the origin of collected samples. Indeed, a reliable and versatile analytical approach is necessary to overcome these challenging problems.Mass spectrometry (MS) is a wide used analytical technique in which ionized chemical species are sorted on the basis of their mass-to-charge ratio (m/z). MS is commonly used with qualitative and quantitative purposes, representing a high-performances instrument to be used in several fields. Moreover, mass spectrometers can be easily coupled to gas chromatography (GC) and liquid chromatography (LC), thus resulting in an excellent sensitive and selective tool to perform environmental analysis. Currently, MS-based methods are commonly used for environmental analyses allowing an accurate and reproducible identification and quantitation of a huge variety of pollutants, even in low amounts. This book covers several MS-based approaches for environmental analysis, illustrating a first overview of commonly used platforms followed by some interesting examples of applications. The Section 1 reports current trends in environmental analysis, highlighting the state-of-the-art of international legislations and future perspectives. The Section 2 is an overview of MS-based methods and platforms currently used for environmental analysis. MS-based metabolomics, lipidomics and other classical approaches, along with their features and limitations, are described. Moreover, some specific techniques such as the targeted parallel reaction monitoring, are included. Finally, the Section 3 contains recent and innovative applications of MS-based methods for environmental analysis. Among others, MS-based approaches have been used for the multiple screening of 90 emerging contaminants in liquid and solid environmental matrices, and for the detection of pollutants as alkanolamines, thallium and pesticides.
