Download or read book Applied Atomic Spectroscopy written by E. L. Grove and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the first appearance of the classic The Spectrum Analysis in 1885 to the present the field of emission spectroscopy has been evolving and changing. Over the last 20 to 30 years in particular there has been an explosion of new ideas and developments. Of late, the aura of glamour has supposedly been transferred to other techniques, but, nevertheless, it is estimated that 75% or more of the analyses done by the metal industry are accomplished by emission spectroscopy. Further, the excellent sensitivity of plasma sources has created a demand for this technique in such divergent areas as direct trace element analyses in polluted waters. Developments in the replication process and advances in the art of pro ducing ruled and holographic gratings as well as improvements in the materials from which these gratings are made have made excellent gratings available at reasonable prices. This availability and the development of plane grating mounts have contributed to the increasing popularity of grating spectrometers as com pared with the large prism spectrograph and concave grating mounts. Other areas of progress include new and improved methods for excitation, the use of controlled atmospheres and the extension of spectrometry into the vacuum region, the widespread application of the techniques for analysis of nonmetals in metals, the increasing use of polychrometers with concave or echelle gratings and improved readout systems for better reading of spectrographic plates and more efficient data handling.
Download or read book Trace Element Analysis in Biological Specimens written by R.F.M. Herber and published by Elsevier. This book was released on 1994-05-19 with total page 591 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major theme of this book is analytical approaches to trace metal and speciation analysis in biological specimens. The emphasis is on the reliable determination of a number of toxicologically and environmentally important metals. It is essentially a handbook based on the practical experience of each individual author. The scope ranges from sampling and sample preparation to the application of various modern and well-documented methods, including quality assessment and control and statistical treatment of data. Practical advice on avoiding sample contamination is included. In the first part, the reader is offered an introduction into the basic principles and methods, starting with sampling, sample storage and sample treatment, with the emphasis on sample decomposition. This is followed by a description of the potential of atomic absorption spectrometry, atomic emission spectrometry, voltammetry, neutron activation analysis, isotope dilution analysis, and the possibilities for metal speciation in biological specimens. Quality control and all approaches to achieve reliable data are treated in chapters about interlaboratory and intralaboratory surveys and reference methods, reference materials and statistics and data evaluation. The chapters of the second part provide detailed information on the analysis of thirteen trace metals in the most important biological specimens. The following metals are treated in great detail: Aluminium, arsenic, cadmium, chromium, copper, lead, selenium, manganese, nickel, mercury, thallium, vanadium and zinc. The book will serve as a valuable aid for practical analysis in biomedical laboratories and for researchers involved with trace metal and species analysis in clinical, biochemical and environmental research.

Beginning with a brief introduction and discussion of statistical evaluation of data, the subsequent chapter looks at trace analysis in general, with its essentials and terminology. Another section introduces sampling and preparation of foodstuffs such as wheat, potato, vegetables and milk. This is followed by descriptions of the various spectrometric techniques (atomic absorption, atomic emission, atomic fluorescence) that are available. Plasma techniques for both optical emission and mass spectrometry are presented, as are nuclear activation analysis and X-ray methods. A comparison of the various analytical techniques is provided, and a separate chapter handles speciation analysis. Finally, procedures for determining essential and toxic elements such as arsenic, iron, selenium and zinc are suggested, using several recent references. Detailed explanations and a simple format will appeal to laboratory technicians and graduate students, as well as more experienced researchers. Comprehensive coverage, coupled with illustrations and a guide to relevant literature and manufacturers, will make Trace Element Analysis of Food and Diet a valuable source of information for anyone working on analysis of trace elements in food, diet or other biological or environmental samples - particularly food engineers, agricultural scientists and government testing agency employees.
Download or read book Handbook of Inductively Coupled Plasma Spectrometry written by Michael Thompson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of our Handbook was written in 1983. In the preface to the first edition we noted the rapid development of inductively coupled plasma atomic emission spectrometry and its considerable potential for elemental analysis. The intervening five years have seen a substantial growth in ICP applications; much has happened and this is an appropriate time to present a revised edition. The basic approach of the book remains the same. This is a handbook, addressed to the user of the technique who seeks direct, practical advice. A concise summary of the technique is attempted. Detailed, theoretical treatment of the background to the method is not covered. We have, however, thoroughly revised much of the text, and new chapters have been added. These reflect the changes and progress in recent years. We are grateful to Mr Stephen Walton, Dr Gwendy Hall and London and Scandinavian Metallurgical Co. Ltd for their contributions. Chapter 3 (Instrumentation) has been rewritten by Mr Walton, the new Chapter on ICP-mass spectrometry has been written by Dr Hall, and London and Scandinavian provided much of the information for the chapter on metals analysis by ICP-AES. These chapters have been integrated into the book, and a conscious effort has been made to retain the unity of style within the book. New material has been added elsewhere in the book, archaeological materials are considered, pre concentration methods and chemometrics covered more fully.

Download or read book Determination of Trace Elements of Metallurgical Interest in Complex Alloy Matrices by Nonflame Atomic Absorption Spectroscopy written by JY. Marks and published by . This book was released on 1977 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic absorption with the high-temperature graphite tube furnace as an atomization source has proven to be particularly versatile in the determination of trace elements in complex alloys such as those used in gas turbine engines. Elements which are harmful to mechanical properties at levels of from 0.1 to 10 ppm include lead, bismuth, thallium, selenium, and tellurium. Indium, antimony, tin, and gallium are harmful at concentrations between 10 and 50 ppm. Accurate and reliable nonflame methods have been established in our laboratory for the determination of all these elements in complex alloys. Proper optimization of several variables is important in obtaining good results. The choice of dissolution medium is important to prevent volatilization losses of trace elements during sample preparation and during the thermal cycle before sample atomization. Selection of proper heating parameters before atomization can be instrumental in reducing background absorption and in realization of best sensitivity. Good alignment of analyte hollow cathode beam with background correction beam is critical for realization of maximum sensitivities. A comparison of the direct nonflame atomic absorption technique with other methods for trace element analysis such as emission spectroscopy, mass spectrometry, and flame atomic absorption after preconcentration shows advantages of speed, accuracy, and versatility. Recent work in our laboratory has suggested that some trace element determinations may be possible using direct atomization of the element from alloy chips. Significant advantages in sensitivity, reduction of background absorption, and speed may result from atomization from metal chips.
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 Quantitative Trace Analysis of Biological Materials written by Hugh A. McKenzie and published by Elsevier Publishing Company. This book was released on 1988 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding of the functions of trace elements in metabolism, whether associated with microorganisms, plants or animals, has advanced considerably during the last twenty years. There are two main aspects of the importance of trace elements in biological materials: first, their toxic effects and secondly, the essential nature of some of the elements for normal growth and health. Research in trace elements and their essential role in biological processes has advanced through several stages, necessitating more and more effective methods of determination. Despite the marked improvements in methods of trace analysis during these twenty years, the ever increasing need for higher sensitivity to meet new demands has meant the greater need, not only for improving the limits of detection, but also for new standard reference materials, better sampling, better sample handling and better design of trace and ultra-trace analysis laboratories. This book focusses on all areas of trace element determination with detailed discussion on all major methods of analysis. Additionally, the determination of concentrations of major toxic and essential trace elements is discussed at length.
