W. Fuller Since the introduction of atomic absorption spectrometry as an analytical technique, by Walsh, in 1953, the use of alternative atomization sources to the flame has been explored. At the present time the two most successful alternatives appear to be the electrothermal atomiser and the inductively- coupled plasma. In this book an attempt has been made to provide the author's views on the historical development, commercial design features, theory, practical considerations, analytical parameters of the elements, and areas of application of the first of these two techniques, electrothermal atomisation.

James The literature of analytical chemistry exhaustively covers the many techniques now available to the analyst. feature common to a l l analyses, is in contrast only sparsely documented. Comparatively few original papers on this subject have been published in the last fifty years; there are very few reviews available, and perhaps as a result sampling is badly neglected in most instructional courses in analytical chemistry. This Monograph will go some way towards filling a gap in the literature and should stimulate interest in the development of sampling as a field of study.

The quality of the printing, reproduction of figures, and the paper itself is excellent, which is refreshing in these days of shortcuts and photoreplication. The senior reporter and his colleagues are to be congratulated on a demanding assignment in which a very high standard of performance has been set and consistently achieved".- Journal of Medicinal Chemistry, reviewing Vol. 8 Hardcover 704pp 0 85186 095 8 Price f70.00 ($149.00) Annual Reports On the Progress of Chemistry Vol.77 Annual Reports provides for the general reader critical coverage of the significant advances in the major areas of chemistry on an annual basis. From 1980, Section A became devoted solely to inorganic chemistry and therefore exhibited enhanced coverage of this area compared with previous years. Section C, a new Annual Reports volume on physical chemistry has been introduced which consists of authoritative critical accounts of progress in major areas by acknowledged experts. Section B covers organic chemistry.

A 20ns energy pulse from a laser is focused on to a 5pm spot on the sample. About 10pm3 of sample is vapourised, the ions extracted, accelerated and directed into a time of flight mass analyser. The ions are detected by an electron multiplier and the output is displayed on a storage oscilloscope and held in a transient recorder.Cambridge Consultants Ltd. Circle 516.
