Recent interest in cation metabolism in clinical medicine makes this short monograph on spectrochemical analysis a timely contribution. By starting with the common principle that all spectroanalyses are derived from transitions between energy states, the authors provide a basis for understanding the phenomena of atomic emission and atomic absorption. After a brief history of spectrochemical analysis, they proceed smoothly into discussions of elementary atomic structure, the origin of emission and absorption spectra, and the properties of visible and ultraviolet radiation. Persons with limited background in spectrochemistry often have the impression that detection limits of chemicals are infinitely low, hence the chapter which delineates limitations in spectrochemical analysis is of special interest. The section on emission analysis begins with a very thorough discussion of excitation systems, including methods of introducing a sample into the flame.
The comparatively new, but clinically important, field of atomic absorption analysis occupies a good portion
