Book Description
In recent years the x-ray fluorescence technique has become increasingly important in modern analysis and production control; it can be classified as a spectroscopical method for the determination of the elemental com position. Many articles treat this method; however, there exists no modern textbook suitable for the beginner as well as the practician and theoretician. In this monograph the author intends to fill this need to present the prin ciples of x-ray fluorescence analysis and to develop a theoretical under standing of the technique. Both principles and theory w.ill be treated exten sively, for they are the basis for successful practical application of the method. X-ray fluorescence, on the other hand, is often carried out exclusively because of its practical usefulness. For this reason theoretical investigations are used exclusively as a basis for practical work and the multitude of applications, which constitute the value of the x-ray fluores cence method, will be explained on the basis of simple theory. The idea to write this monograph originated and developed when efforts to train coworkers required a more complete treatise. I would like to thank the elBA Aktiengesellschaft in Basel, where this work originated, for generous support and permission to publish the book. The head of the Physics Department, Dr. E. Ganz, and my colleagues have contributed to this book by providing a stimulating working atmosphere. I am grateful to my associates, in particular Messrs. E. Eng, S. Gasser, and H. R.

Book Description
Since the first edition of this book was published early in 1970, three major developments have occurred in the field of x-ray spectrochemical analysis. First, wavelength-dispersive spectrometry, in 1970 already securely established among instrumental analytical methods, has matured. Highly sophisticated, miniaturized, modular, solid-state circuitry has replaced elec tron-tube circuitry in the readout system. Computers are now widely used to program and control fully automated spectrometers and to store, process, and compute analytical concentrations directly and immediately from ac cumulated count data. Matrix effects have largely yielded to mathematical treatment. The problems associated with the ultralong-wavelength region have been largely surmounted. Indirect (association) methods have extended the applicability of x-ray spectrometry to the entire periodic table and even to certain classes of compounds. Modern commercial, computerized, auto matic, simultaneous x-ray spectrometers can index up to 60 specimens in turn into the measurement position and for each collect count data for up to 30 elements and read out the analytical results in 1--4 min-all corrected for absorption-enhancement and particle-size or surface-texture effects and wholly unattended. Sample preparation has long been the time-limiting step in x-ray spectrochemical analysis. Second, energy-dispersive spectrometry, in 1970 only beginning to assume its place among instrumental analytical methods, has undergone phenomenal development and application and, some believe, may supplant wavelength spectrometry for most applications in the foreseeable future.
