# Book Review Spectrochemical Analysis by Atomic Absorption and Emission. By L. H. J. Lajunen

код для вставкиСкачатьwith which the author has been concerned in the past, the application of statistical methods to potentiometric titration. The book ends with an appendix consisting of seven short sections, which include definitions of the most important terms used in statistics and brief explanations of matrix algebra, partial differentiation, the calculation of expectation values, and various minor mathematical theorems. The author has set out to describe the processes of data compilation and analysis that take place inside the “black box” (the microcomputer and associated application programs), and in particular to draw attention to the problems and difficulties of data handling. The reader is specifically warned about the possible pitfalls that await the inexperienced user when data are interpreted with the help of such a “black box”. The book fulfills this task very well, and it should be of considerable value to all who use microcomputers and application programs for statistical data analysis. I can recommend it unreservedly for such readers. Horst Hippier Institut fur Physikalische Chemie der Universitat Gottingen (FRG) Spectrochemical Analysis by Atomic Absorption and Emission. By L. H. J. Lajunen. The Royal Society of Chemistry, London, 1992. XII, 242 pp., paperback E 18.50.--ISBN 0-86 186-873-8 This book, which is intended for students and teachers of analytical chemistry, describes the state of knowledge in atomic spectroscopy in the early 1990s. Following a short historical sketch and a general explanation of the terms used, the fundamental theory is presented. This forms the basis for a clearly understandable description of various analytical techniques, ranging from flame atomic absorption spectroscopy (flame-AAS) through graphite furnace AAS (GFAAS) and other AAS methods, inductively coupled plasma atomic emission spectroscopy (ICP-AES), and ICP-mass spectrometry (ICP-MS), to atomic fluorescence spectroscopy. For each technique the basic instrumentation is described first, followed by the capabilities, problems, and ways of solving them. The lengths of the chapters reflect the relative importance of the different methods. Thus the most extensive chapters are those on the three most important routine techniques, namely flame-AAS, graphite furnace AAS, and plasma-AES. Also included, however, are short descriptions of recently developed techniques such as ICP-MS and the different types of sample introduction systems used (although here the book does not go into much detail, and also some small errors have crept in, such as an incorrect figure showing a mass spectrum on page 197). A very positive feature of the book is that the author does not waste time on trivia but concentrates on important relationships and an overall view, though without neglecting the problems. For example, a separate chapter is devoted to sample preparation, ranging from sample acquisition through digestion techniques to methods of separation and enrichment. The clear presentation of the material is also greatly helped by the detailed and well-arranged list of contents and the many figures (148) and tables (46), which both support and amplify the information in the text. To round off the book there is a section in which the different atomic spectroscopy methods are summarized and compared, together with a list of books for further reading and of the most important relevant journals. The book can be recommended for everyone who wishes to learn about the capabilities and limitations of analysis by atomic spectroscopy. It is especially suitable for students with interests in analytical chemistry, for whom it offers a clearly understandable and thorough grounding i n modern atomic spectroscopy. It is to be hoped that it will reach a wide readership, as it covers a broad range of subject matter in a very readable form.
