X-ray fluorescence analysis (XRF) is one of the most objective and adequate methods for studying the composition of a substance, since it is direct. The object under study is subjected to an exciting effect - it can be a stream of electrons, protons, x-rays or gamma radiation with energy sufficient to transfer the atoms of the sample into an excited state. The excitation energy is such that when atoms go to the ground state, fluorescence occurs in the X-ray range. The spectral composition of this radiation uniquely corresponds to the elemental composition of the object. Apparatus for spectral analysis (spectrometers) in one way or another decompose fluorescent radiation into a spectrum, which is studied and analyzed using a methodological and mathematical apparatus.
The physical foundations of the method were developed in the first half of the 20th century. In the process of developing the theory and practice of the XRF method, the areas of its application covered almost all aspects human activity: science, technology, agriculture. It is needed wherever you need to quickly and accurately determine chemical composition substances. It is also important that the object does not suffer from exposure to X-rays, which made the use of the method indispensable in art history, forensic science, and expertise.
However, despite the high demand for the XRF method, its application for a long time remained available only to the laboratories of large and wealthy enterprises and universities. The fact is that almost until the end of the last century, the development of the XRF hardware base followed the path of increasing the power of the spectrum excitation source: an X-ray tube, a radioactive isotope, a linear accelerator, a synchrotron. For example, the weight of only a high-voltage power source for an X-ray tube with a power of several thousand watts (typical power for such devices) was tens and hundreds of kilograms. Such a powerful X-ray flux required reliable biological protection; the generated heat had to be removed using water cooling. Thus, the spectrometer was a bulky unit that consumed a lot of energy and required a separate room, as well as qualified personnel for operation and for Maintenance. The price of such a device reached many hundreds of thousands of dollars, which, with high operating costs, made the device inaccessible to laboratories of small and medium-sized enterprises. In addition, due to the complexity and high cost, the number of manufactured devices was not enough to meet demand.
Obviously, to introduce the XFA method into wide analytical practice, a fundamentally different approach is needed. The new approach is based on theoretical and experimental work K. Anisovich and employees. The works are devoted to the calculation of luminosity and energy resolution for the main schemes of crystal-diffraction spectrometers. The results of theoretical calculations, confirmed experimentally, exceeded all expectations. It turned out that with a correctly calculated ratio of distances between the circuit elements, the total aperture ratio of spectrometers made according to an optimized X-ray optical scheme (the so-called aperture scheme) exceeds the overall aperture ratio of traditional spectrometers by 2-3 orders of magnitude. In practice, this meant that in order to obtain analytical characteristics comparable to those of commonly used high-power stationary spectrometers, an X-ray source hundreds of times less powerful was sufficient. desktop device, devoid of the disadvantages of bulky and expensive installations. It must be said that the correctly selected ratio of distances and angles of the X-ray optical scheme made it possible to level out another drawback of classical crystal diffraction devices - a strong dependence of readings on the inaccuracy of the sample setting. But most importantly, it became possible to start serial production of inexpensive X-ray crystal diffraction spectrometers accessible to small laboratories. In 1989 K.V. Anisovich founded and headed NPO "SPEKTRON", whose main goal was to meet the huge demand for X-ray spectrometers available to the mass user. It was this ambitious requirement - the introduction of XRF into mass analytical practice - that became the corporate slogan of the enterprise, the idea to which all its activities, starting with the smallest things, were subordinated.
