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 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.

Download or read book Methods for the Determination of Metals in Environmental Samples written by Us Epa and published by CRC Press. This book was released on 1992-08-20 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for the Determination of Metals in Environmental Samples presents a detailed description of 13 analytical methods covering 35 analytes that may be present in a variety of sample types. The methods involve a wide range of analytical instrumentation including inductively coupled plasma (ICP)/atomic emission spectroscopy (AES), ICP/mass spectroscopy (MS), atomic absorption (AA) spectroscopy, ion chromatography (IC), and high performance liquid chromatography (HPLC). The application of these techniques to such a diverse group of sample types is a unique feature of this book. Sample types include waters ranging from drinking water to marine water, in addition to industrial and municipal wastewater, groundwater, and landfill leachate. The book also includes methods that will accommodate biological tissues, sediments, and soils. Methods in this book can be used in several regulatory programs because of their applicability to many sample types. For example, ICP/AES, ICP/MS, and AA methods can be used in drinking water and permit programs. Methods applicable to marine and estuarine waters can be used for the EPA's National Estuary Program. Terminology is consistent throughout the book, an important feature especially for the quality control sections where standardized terminology is not yet available. Methods for the Determination of Metals in Environmental Samples is an indispensable methods guide for all environmetal labs, wastewater labs, drinking water labs, lab managers, consultants, and groundwater engineers.
