This textbook is an outgrowth of the author's experience in teaching a course, primarily to graduate students in chemistry, that included the subject matter presented in this book. The increasing use and importance of atomic spectroscopy as an analytical tool are quite evident to anyone involved in elemental analysis. A number of books are available that may be considered treatises in the various fields that use atomic spectra for analytical purposes. These include areas such as arc-spark emission spectroscopy, flame emission spectroscopy, and atomic absorption spectroscopy. Other books are available that can be catalogued as "methods" books. Most of these books serve well the purpose for which they were written but are not well adapted to serve as basic textbooks in their fields. This book is intended to fill the aforementioned gap and to present the basic principles and instrumentation involved in analytical atomic spectro scopy. To meet this objective, the book includes an elementary treatment of the origin of atomic spectra, the instrumentation and accessory equipment used in atomic spectroscopy, and the principles involved in arc-spark emission, flame emission, atomic absorption, and atomic fluorescence. The chapters in the book that deal with the methods of atomic spectro scopy discuss such things as the basic principles involved in the method, the instrumentation requirements, variations of instrumentation, advantages and disadvantages of the method, problems of interferences, detection limits, the collection and processing of the data, and possible applications.

There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy. Hamlet There exists a fairly large number of textbooks concerned with spectrochemical analysis. Most of them deal with practical applications and instrumental factors, and provide the reader with the knowledge indispensable for conducting analyses with the help of emission spectra. Practical knowledge and experience are indeed important requisites for success fully exploiting the spectrochemical method in the field of analytical chemistry. As the method is essentially empirical, it is, in principle, a simple one, provided that we succeed in exciting all samples in an identical manner; for then, relative intensities of spectral lines can serve as the 'weights' by which to measure amounts of elements. However, creating the required constancy of excitation conditions is hampered by the very nature of the sample, whose composition profoundly influences the excitation characteristics of the light source. Therefore, spectrochemists are inevitably engaged in all the processes that determine the radiation output of the light source for a given sample. Dealing, with this ensemble of processes, that is, with 'excitation' in the widest sense, is the object of this book (cf. § 1. 1). The reader will seek in vain for enumerations of practical rules that would tell him how to tackle a particular analysis problem.
