This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The versatility of flow injection as a sample manipulation technique is demonstrated in the automatic handling of certain interferences. Methods are presented for the in-line addition of interferent suppressors and the in-line removal of interferents using ion-exchange separation. This methodology is demonstrated in: (i) the addition of potassium iodide to reduce the analyte to a common oxidation state prior to hydride formation, for the determination of arsenic and antimony; (ii) the in-line addition of tellurium to increase the tolerance of the interference of certain noble metals; and (iii) the in-line separation of the interference of certain base metals using ion-exchange separation.

Book excerpt: Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. Atomic absorption is so sensitive that it can measure down to parts per billion of a gram (μg dm-3) in a sample. The technique makes use of the wavelengths of light specifically absorbed by an element. They correspond to the energies needed to promote electrons from one energy level to another, higher, energy level. Atomic absorption spectrometry has many uses in different areas of chemistry. Examining metals in biological fluids such as blood and urine, Monitoring our environment - e.g. finding out the levels of various elements in rivers, seawater, drinking water, air, petrol and drinks such as wine, beer and fruit drink. In some pharmaceutical manufacturing processes, minute quantities of a catalyst used in the process (usually a metal) are sometimes present in the final product. By using AAS the amount of catalyst present can be determined. Many raw materials are examined and AAS is extensively used to check that the major elements are present and that toxic impurities are lower than specified - e.g. in concrete, where calcium is a major constituent, the lead level should be low because it is toxic. By using AAS the amount of metals such as gold in rocks can be determined to see whether it is worth mining the rocks to extract the gold. Atomic Absorption Spectroscopy aims to cover all major topics which are required to equip scholars with the recent advancement in this field. The book provides a systematic treatment of combining flow injection methods with all fields of atomic absorption spectrometry (AAS) including flame, hydride generation and electrothermal AAS.
Download or read book Design and Optimization of a Flow Injection Hydride Generator and Its Use for Automated Standard Additions written by and published by . This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A continuous flow approach to the generation of the gaseous covalent hydrides for the determination of certain Group IV, V and VI elements is described. A flow injection hydride generator in which the sample is injected into an acidic carrier stream, which is subsequently merged with the reductant, has been developed. This apparatus allows rapid analysis, ease of automation and simple in-line handling of interferences. The tried and tested method of standard additions is automated and simplified in the described apparatus. The determination of bismuth in the presence of palladium is used to demonstrate the feasibility of the flow injection approach to standard additions. The apparatus has also been optimized for the determination of antimony, arsenic, bismuth, selenium and tellurium yielding detection limits of 10, 8, 2, 6 and 3 ng/ml, respectively. Germanium, lead and tin are also measurable using the apparatus, however, the detection limits achieved were similar to those obtainable by flame atomic absorption spectrometry.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and detailed description of the most widely used sample introduction techniques in atomic spectroscopy is presented in this volume. Comprising twelve separate chapters, the book describes the theory in detail, and gives an account of techniques and selected applications of sample introduction systems. The first chapter is a general overview on sample introduction. The remaining eleven chapters are each devoted to a specific sample introduction and deal with the basic principles, describe the system, advantages, disadvantages and selected applications. Systems described are: pneumatic nebulization, electrothermal vaporization, laser ablation, impaction/electrostatic precipitation, slurry atomization, ultrasonic and thermospray nebulization, hydride generation, chromatographic, spark and arc, low-pressure discharges, flow injection analysis and direct solid introduction. Each chapter is suitable for a separate discussion. Being a unique textbook in this field, Sample Introduction in Atomic Spectroscopy should prove invaluable for courses at graduate level.

Available in PDF, EPUB and Kindle. Book excerpt: Antimony, arsenic, bismuth, germanium, lead, selenium, tellurium and tin just some of the elements which, in trace amounts, have biological, environmental and technological importance. Hydride Generation Atomic Absorption Spectrometry describes one of the most accurate analytical techniques for trace analysis of these elements, sensitive to picogram levels. Over the last decade, significant instrumental and methodological progress has led to HG-AAS being widely applied to an extensive range of sample types. In this first comprehensive monograph on HG-AAS, the authors treat both theoretical and experimental aspects of the subject in a critical and in-depth manner. Hydride Generation Atomic Absorption Spectrometry is divided into two parts, with the theoretical background and experimental approach covered in Part I. Part II discusses the methodology and analytical applications to a wide range of fields, arranged in an easy to use element-by-element format. Over 1500 references provide an exhaustive coverage of the vast literature on HG-AAS, making Hydride Generation Atomic Absorption Spectrometry the premier reference source on this important technique. Hydride Generation Atomic Absorption Spectrometry will be an invaluable reference work for all analysts using hydride generation for AAS or for other spectrometric methods. It will also be of great interest to researchers and students working in atomic spectrometry and trace analysis.
