This book was released on 2013-09-26 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments clearly indicate that speciation studies in biological and environmental matrices are much more important than the total element determination due to the tremendous difference in bioavailability and toxicity of various chemical forms of a particular element. Different separation-detection techniques and hyphenated systems—each with its own advantages and disadvantages with respect to precision, sensitivity and detection limit—have been developed for the identification and quantification of the species present in systems at ultra-trace levels. This book aims to evaluate the speciation analysis in depth and present a comprehensive review of state-of-the-art analytical approaches used for the speciation of elements in environmental samples.

Download or read book Trace Metal Analysis and Speciation written by I.S. Krull and published by Elsevier. This book was released on 1991-10-08 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to describe the most recent advances in areas of analytical chemistry that relate to the trace determination of metals and inorganics, as well as their distribution and forms (species) present, sample dependent. Analytical approaches are described that encompass a number of separation methods, such as gas and high performance liquid chromatography, interfaced with selective and sensitive detection methods that become unique for metal species/forms present in various samples. Hyphenated techniques are emphasized, such as interfacing HPLC with plasma induced emission spectroscopy, electrochemistry, post-column reaction chemistry, etc. Each chapter describes the latest instrumental and methodology advances that utilize some form of chromatography together with element-specific detection or mass spectrometry to provide absolute identification of the specific species of a metal present in various samples. The book will be of value to those concerned with the determination of trace levels of individual metal species present or suspected present in any given sample and to those involved in trace metal toxicology, metabolism of metal-containing drugs or chemicals, environmental exposures to metals and chemical speciation of real world samples. Government regulatory laboratories striving to detect and determine absolute levels of a metal species in any regulated sample will be interested in this volume, as will academic institutes involved in environmental toxicology, environmental chemistry, metal-DNA/protein interactions and researchers working with metal species.

Download or read book Modern Advancements in Elemental Speciation written by Douglas Dennis Richardson and published by . This book was released on 2007 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elemental speciation is the investigation of the chemical form of metal and non- metal containing species in environmental and biological systems for the determination of species specific essentiality and toxicity. Speciation analysis is performed by combining modern separation techniques with state-of-the-art element specific mass spectrometry. Separation techniques used in this work include: capillary electrophoresis (CE), high performance liquid chromatography (HPLC) and gas chromatography (GC). Inductively coupled plasma mass spectrometry (ICPMS) is the instrument of choice for ultra-trace elemental speciation analyses due to the excellent sensitivity and selectivity specific to this mass spectrometer. Modern innovations in analytical instrumentation specific for elemental speciation have provided researchers with resources for the development of new hyphenated techniques and analytical methods. The specific goal of this dissertation is to describe modern advancements specific to elemental speciation. In the first section a novel interface coupling CE and hydride generation with ICPMS detection for arsenic speciation is described. The novel concentric tube interface design allowed for the separation, hydride generation, and detection of four arsenic species in less than 10 minutes. The majority of this dissertation focuses on method development for the analysis of organophosphorus chemical warfare agent (CWA) degradation products. Recent increases in worldwide terrorist activity as well as the threat of chemical weapon attacks have led to the demand for rapid and reliable analytical techniques for CWA analysis. Methods utilizing both HPLC and GC separation techniques couple with 31P element specific detection with ICPMS for the analysis of organophosphorus chemical warfare agent degradation products are described. These works are the first to utilize 31P detection with ICPMS for the analysis of chemical warfare agent degradation products.
Download or read book Sample Handling and Trace Analysis of Pollutants written by Damia Barcelo and published by Elsevier. This book was released on 2000-03-08 with total page 1151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an updated, completely revised version of a previous volume in this series entitled: ENVIRONMENTAL ANALYSIS -- Techniques, applications and quality assurance. The book treats different aspects of environmental analysis such as sample handling and analytical techniques, the applications to trace analysis of pollutants (mainly organic compounds), and quality assurance aspects, including the use of certified reference materials for the quality control of the whole analytical process. New analytical techniques are presented that have been developed significantly over the last 6 years, like solid phase microextraction, microwave-assisted extraction, liquid chromatography-mass spectrometric methods, immunoassays, and biosensors. The book is divided into four sections. The first describes field sampling techniques and sample preparation in environmental matrices: water, soil, sediment and biota. The second section covers the application areas which are either based on techniques, like the use of gas chromatography-atomic emission detection, immunoassays, or coupled-column liquid chromatography, or on specific application areas, like chlorinated compounds, pesticides, phenols, mycotoxins, phytotoxins, radionuclides, industrial effluents and wastes, including mine waste. Validation and quality assurance are described in the third section, together with the interpretation of environmental data using advanced chemometric techniques. The final section reports the use of somewhat advanced analytical methods, usually more expensive, less routinely used or less developed, for the determination of pollutants.
Download or read book Flow Analysis with Atomic Spectrometric Detectors written by A. Sanz-Medel and published by Elsevier. This book was released on 1999-02-25 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow Analysis (FA) offers a very convenient and fast approach to enhance and automate 'preliminary steps' of analysis (sample dissolution, pretreatments, preconcentrations, etc.) for atomic spectrometric detectors (ASD). Moreover, flow manifolds can ease the well-known problem of sample introduction/presentation to atomisers or even expand the classical scope of atomic/elemental information, characterizing atomic spectrometry, into the realm of molecules and metal-compounds analysis (e.g. by resorting to coupled separation techniques). All these facts could explain both the extraordinary interest for research and the great importance for practical problem-solving achieved nowadays by FA-ASD.On the threshold of the new millennium when plasma emission and mass spectrometry are so important and popular, the editor considered it timely to produce a book which covers all present atomic detectors and techniques where FA has been or can be advantageously employed. The book has been conceived in three separate parts:Part I gives the fundamental, instrumentation and potential of FIA as a most versatile sample presentation/introduction system for atomic spectrometry.Part II provides a modern account of fundamentals, possibilities and applications offered by flow analysis to atomic spectrometry for on-line sample pretreatments, separations and preconcentrations.Part III deals with applications of FA-ASD combinations to analytical problem-solving in most varied fields and situations.This monograph integrates the most popular aspects of FIA, its new developments for sample on-line treatments and on-line non-chromatographic and chromatographic separations (all typical 'flow analysis') in connection with all branches of analytical atomic spectrometry. Thus, academics, researchers and routine users of analytical atomic spectrometry will find this book invaluable.
Download or read book Methods for the Analysis of Organometallic Compounds in Wastes written by WR. Blair and published by . This book was released on 1988 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organometallic compounds occur in the environment as a result of anthropogenic and biogenic processes. Since organometals are often much more toxic than the corresponding inorganic forms of metals, it is important to be able to speciate the forms of metals in environmental samples at ultratrace levels. Chemical speciation methods, based on the use of chromatographic separations followed by element-selective detection, have been developed in our laboratories and elsewhere. These methods, described in part in this paper, are helping us to measure organometal species at their action levels (down to parts-per-trillion levels) in environmental matrices, leading to a better understanding of environmental occurrence, fate, effects, and transformation. New methods for nondestructive analysis of metal species on surfaces are under development.
