Possibility to determine groups of elements without readjustment of crystal-analyzer. Exceptionally high resolution of the Koshua X-ray optical scheme with crystal-analyzer quartz 1011. Developed mathematical support. Principle of analyzer operation is based on the excitation of the fluorescent radiation of sample atoms being under examination by radiation coming from an X-ray tube. Spectrum decomposition of the fluorescence radiation is performed according to Cauchois method. The fluorescence radiation focused by analyzing crystal and standard line are marked on Rowland focal circle. Then, they are recorded by X-ray radiation detector in turn. The intensity of the fluorescent irradiation with a particular wavelength is directly proportional to the chemical element concentration in the material under examination.

The XRF analyzer BRA-135F is an energy dispersive spectrometer which can simultaneously determine the presence of up to twenty chemical elements - from 9F to 92U - in the analyzed sample. Samples can be in liquid, solid, powdered or deposited on a substrate. The analyzer captures concentrations from tenths of mg/kg. The model BRA-135F performs quantitative/semi-quantitative spectral analysis of steel and alloys. It also performs spectral analysis of oil, petroleum and other petroleum products, detecting in their composition even the smallest concentrations of impurities of various metals. The vacuum sample chamber and ultra-slim detector inlet provides a low detection limit in the range of light elements from 9F to 17Cl. The high-performance silicon drift detector (SDD) with an energy resolution of less than 135eV allows the separation of spectral lines of almost all elements, which makes the analysis of complex multicomponent substances (high-alloy steels, precision alloys, polymetallic ores, etc.) possible.

The INFRASKAN 4200 analyzer has been tested at the D.I. Mendeleev VNIIM, entered into the unified State Register of measuring instruments under No. 83050-21.

A liquid flask with an adjustable layer thickness of the liquid under study is made in the form of an optical-mechanical attachment installed in the cuvette compartment of the FT-801 spectrometer. It contains focusing optics, removable holders of two windows-substrates with a diameter of 10 mm and two adjusting screws placed on the upper panel of the console housing and designed to set the required gap between the windows. A liquid of any degree of viscosity is pre-applied in the form of a small drop to the lower window and then, in the process of smooth convergence of the windows, evenly fills the gap between them. By rotating the adjusting screws and observing the transmission spectrum online, the user has the opportunity to set the desired thickness of the liquid layer, guided by the overall intensity of the entire spectrum or by the intensity of specific absorption bands. In the presence of calibration, which is easy to create using the ZaIR 3.5 program for several samples with a known concentration, the cuvette allows quantitative measurements. The flask is indispensable in the analysis of mixtures containing impurities in small proportions.

The sample heating system is designed to expand the capabilities of standard set-top boxes NPVO-ZDO and NPVO-A. It consists of a heated replaceable frame with a diamond prism and a temperature controller unit. For most solid samples in the heated state, it is possible to obtain a much more pronounced NPV spectrum than in the cold state. This makes it possible to increase the sensitivity of the method several times. The properties of some substances and compounds change dramatically with an increase in temperature, chemical interaction processes between components, their decomposition, oxidation in air, etc. may occur. If changes in the chemical composition of a substance occur during heating, a set of spectra corresponding to the kinetics of the process can be obtained with the help of an NPVO prefix with a diamond thermocell and a temperature controller, which is essential expands the possibilities of the method in research.
