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.

Instrumental neutron activation analysis is a technique of trace analysis using measurements of radioactivity induced in the sample by exposure to a source of neutrons. The induced activity is measured by the emitted gamma radiation. Each gamma emitter can then be identified by the energy of the photopeaks produced as the nuclide decays and by the half-life of the neutron-induced activity. A complex computer program GAMANAL has been used to accomplish the major tasks of nuclide identification and quantification. The nuclide data output from GAMANAL is processed by a second computer code NADAC, which develops elemental abundance data from disintegration rates observed. The methods are those employed at the Livermore Pool-Type Reactor in support of the environmental research trace element analysis program. Among the procedures described and discussed are sample preparation, irradiation, analysis, and application of the technique.

This research deals with radiochromatographic separations in neutron activation analysis of trace elements in serum. Understanding the metabolic roles of trace elements as well as their toxicological effects in biological systems has been limited by the sensitivity and selectivity of existing analytical techniques. The lack of human serum concentration data for many trace elements prevents optimum clinical utilization of this extremely powerful diagnostic tool. Neutron activation analysis has extremely low limits of detection for a large number of elements. However, interference from those elements present in human serum at relatively high levels must be eliminated before even a high-resolution solid state detector can be effective. The utilization of high sensitivity sodium iodide detectors requires still more separation. Chromatographic separations of metal chelates were developed for both pre- and post-irradiation separations. Quantitative elution from the gas chromatographic column for fluorine substituted beta-diketonate complexes of Cr, Cu, Mn, Fe, Be, Lu, and Gd was studied; recoveries between 52 and 92% were found. Extensive studies of decomposition and adsorption losses in the system are reported. Construction and evaluation of various sampling systems, transfer lines, and counting geometries are included. A completely reversible counting geometry for radioactive metal chelates using wide-range temperature and carrier gas control to trap and subsequently release eluate fractions is described. Also included is an apparatus for carrying out chelate separations from solutions whose large volumes preclude gas chromatographic injection. The successful use of a chelating ion exchange resin in human serum neutron activation analysis is reported. Operating conditions which optimize sodium removal with respect to sample loss are described.
