Plasma Sources for MS Optically measuring thermal phenomena

Inductively Coupled and Microwave Induced Plasma Sources for Mass Spectrometry E. Hywel Evans, Jeffrey J. Giglio, Theresa M. Castillano, and Joseph A. Caruso Royal Society of Chemistry Blackhorse Road, Letchworth Herts SG6 1HN, United Kingdom 1995, 108 pp., £32.50

Evans and his colleagues have developed a very readable, concise monograph on ICP and MIP sources for MS. This book reads in a uniform voice—a feature that is frequently absent in collaborative efforts of several authors. By and large, the goal presented in the preface, of "being a useful source of information for those seeking to interface chromatographic and other sample introduction techniques with plasmas," is well met. Excellent overviews of atmosphericpressure and reduced-pressure ICPs and MIPs are presented; a balanced treatment is given of the theoretical and practical aspects of using argon, helium, nitrogen, and other plasmas. This book, of course, is not intended to present a large body of hitherto unreported findings; nearly all the information is in the original literature. The topics are arranged logically, and each section presents a fair amount of rationale for the reader to consider the device discussed as being a better mousetrap. Although the treatment repeats ideas presented elsewhere, a particularly note486 A

worthy discussion is provided on the gas dynamics of ion-sampling interfaces commonly used in the field. This short section does a great job of briefing the applications-oriented user of ICPMS on the subtleties and complexities of what is taking place at the ion-sampling interface. One of the book's strengths is the inclusion of numerous figures that depict actual construction of torch and interface devices; the detail in these figures is certainly adequate for the interested scientist to fabricate similar devices in-house. Although the authors' contributions to this research area are noteworthy, one is left with the impression that the book is mainly a review of the accomplishments of the authors and collaborators.
