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.

Download or read book Application of High Performance Liquid Chromatography mass Spectrometry to Environmental Analysis written by Leon D. Betowski and published by . This book was released on 1989 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: High performance liquid chromatography (HPLC) coupled with mass spectrometry (MS) is described for the analysis of samples for environmental pollutants. During the course of this work different techniques were used to increase both the sensitivity and specificity of HPLC/MS. These included the utilization of two different interfaces for the mass spectrometer - the thermospray and the particle beam systems. Refinements to the thermospray system were made with the use of a wire-repeller to enhance sensitivity and also to increase the structural information obtained from mass spectra. The operation of the instrument in the discharge negative ionization mode further increased the specificity of these techniques as did the use of a triple quadrupole mass spectrometer in the HPLC/MS system. Two different sets of compounds were used in this study. Organic dyes were used to test the improvements in the system. Since work was performed with dyes previously and since dye compounds encompass a variety of structural functionalities, the dyes made good test compounds. Chlorinated herbicides were studied in an effort to analyze for these compounds directly without having to prepare derivatives before separation.

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.

This book was released on 2015-02-03 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for high-throughput separations in food and environmental research that are able to cope with the analysis of a large number of compounds in very complex matrices. Whereas the most common approach for solving many analytical problems has often been high-performance liquid chromatography (HPLC), the recent use of fast or ultra-fast chromatographic methods for environmental and food analysis has increased the overall sample throughput and laboratory efficiency without loss (and even with an improvement) in the resolution obtained by conventional HPLC systems.This book brings together researchers at the top of their field from across the world to discuss and analyze recent advances in fast liquid chromatography-mass spectrometry (LC-MS) methods in food and environmental analysis. First, the most novel approaches to achieve fast and ultra-fast methods as well as the use of alternative and complementary stationary phases are described. Then, recent advances in fast LC-MS methods are addressed, focusing on novel treatment procedures coupled with LC-MS, new ionization sources, high-resolution mass spectrometry, and the problematic confirmation and quantification aspects in mass spectrometry. Finally, relevant LC-MS applications in food and environmental analysis such as the analysis of pesticides, mycotoxins, food packaging contaminants, perfluorinated compounds and polyphenolic compounds are described.The scope of the book is intentionally broad and is aimed at worldwide analytical laboratories working in food and environmental applications as well as researchers in universities worldwide.
