This book was released on 2013 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Employing a continuum radiation source in multi-element analysis is a more attractive method in the development of spectrochemical analysis. Continuum source in simultaneous multi-element analysis, when fully developed, can be used effectively in situations that require routine determination when several elements need to be determined in the same sample. This means that simultaneous detection of analyte absorption signals of different elements in a given sample would be an improved method in multi-element analysis. The need for an appropriate technique for elemental determination in samples which will provide faster analysis with lower detection limits as well as keeping analysis cost reasonable is discussed and the effective spectrometric techniques reviewed. The work was aimed at further development of graphite furnace atomic absorption spectrometry (GFAAS) using a continuum light source, instead of single light source, as a multi-element instrumentation. The aim of this study is to develop a method of atomic absorption for multi-element analysis by employing a continuum source.

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 High Resolution Continuum Source AAS written by Bernhard Welz and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-resolution continuum source atomic absorption spectrometry (HR-CS AAS) is the most revolutionary innovation since the introduction of AAS in 1955. Here, the authors provide the first complete and comprehensive discussion of HR-CS AAS and its application to the analysis of a variety of difficult matrices. Published just in time with the first commercial instrument available for this new technique, the book is a must for all those who want to know more about HR-CS AAS, and in particular for all future users. The advantages of the new technique over conventional line-source AAS are clearly demonstrated using practical examples and numerous figures, many in full color. HR-CS AAS is overcoming essentially all the remaining limitations of established AAS, particularly the notorious problem of accurate background measurement and correction. Using a continuum radiation source and a CCD array detector makes the spectral environment visible to several tenths of a nanometer on both sides of the analytical line, tremendously facilitating method development and elimination of interferences. Conceived as a supplement to the standard reference work on AAS by B. Welz and M. Sperling, this book does not repeat such fundamentals as the principles of atomizers or atomization mechanisms. Instead, it is strictly focused on new and additional information required to profit from HR-CS AAS. It presents characteristic concentration for flame atomization and characteristic mass data for electrothermal atomization for all elements, as well as listing numerous secondary lines of lower sensitivity for the determination of higher analyte concentrations. The highly resolved molecular absorption spectra of nitric, sulfuric and phosphoric acids, observed in an air-acetylene flame, which are depicted together with the atomic lines of all elements, make it possible to predict potential spectral interferences.

Abstract: Abstract of thesis entitled GRAPHITE FURNACE - CAPACITIVELY COUPLED PLASMA - ATOMIC SPECTROMETRY AND INDUCTIVELY COUPLED PLASMA - MASS SPECTROMETRY FOR THE DETERMINATION OF SILICA AND TRACE METALS IN WATER Submitted by Yu Tung Man for the degree of Master of Philosophy at The University of Hong Kong in December 2002 A newly-developed Graphite Furnace - Capacitively Coupled Plasma -Atomic Absorption Spectrometry (GF-CCP-AAS) method was used for the determination of trace silica in aqueous media. The sensitivity for trace silica determination was improved using the GF-CCP-AAS method when compared with traditional method, such as Graphite Furnace - Atomic Absorption Spectrometry (GF-AAS). An Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) method was also used to determine trace elements in drinking water and mineral water samples available in Hong Kong.The GF-CCP-AAS method was developed to meet the demand in the determination of silica for type E-3 and type E-4 high-purity water. The GF- CCP-AES (or FAPES) method with single sample injection was also developed to meet the demand in the determination of silica for type E-2 high-purity water. The detection limits for using the GF-CCP-AAS and FAPES methods are 7.2 ng/L and 3.5 xg/L respectively. The GF-CCP-AAS method can overcome chemical interference which occurs in conventional GF-AAS methods such as matrixes containing sodium chloride, sodium orthophosphate and sodium sulfate but not magnesium sulfate due to the high temperature as the result of using an CCP during atomization. The presence of plasma in the atomization step in GF-CCP-AAS was found to affect the silicon absorption signal. The effects of the solution volume, the peak shape, and the plasma background correction on the absorption signal of silicon using GF-CCP-AAS were studied. Procedures using the fast-drying pre-concentration step were developed, coupled with GF-AAS, GF-CCP-AAS and FAPES. The use of fast-drying pre-concentration GF-CCP-AAS and fast-drying pre-concentration FAPES was found to satisfy the requirements of total silica content in type E-1, type E-1.1 and type E-1.2 high-purity water. The detection limits of GF-CCP-AAS and FAPES coupled with pre- concentration were 0.46 p, g/L and 0.3 pg/L respectively. The extent of the destruction of the quartz and amorphous silica by the plasma was found to be dependent on the size of particles. Amorphous silica with particle size less than 2.5 microns is more completely destroyed by the plasma while quartz silica with particle size greater than 2.5 microns is more favorablydestroyed by the plasma. An ICP-MS method was developed for the determination of elements of concern as listed by the World Health Organization in drinking and mineral water. Different sources of mineral water can be distinguished using isotope ratio analysis under favourable conditions. Magnesium was shown to be the major chemical interference in ICP-MS analysis. Cadmium, antimony, copper nickel, chromium, manganese and uranium were found to show signal suppression in solutions containing magnesium concentrations higher than 30 mg/L.
