Specialized wavelength-dispersive XRF analyzer based on the Cochois scheme is designed for high-precision determination of chemical elements U, Th, Mo, Au, W, Tl, As, Pb as well as other elements in ores, rocks and when developing the technogenic fields. 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.

Vacuum spectrometers are designed for rapid analysis of alloys based on iron, copper, aluminum and other metals in factory and research laboratories, including the determination of elements having analytical lines in the field of vacuum ultraviolet (VUV) (for example, S, P and C in steels).

The generator is designed to produce an electric arc and spark discharge in atomic emission spectral analysis installations. The generator is designed specifically for use in spectral analysis of samples of complex composition for simultaneous determination of impurity and alloying components in a wide range of concentrations.

The MAES analyzer is a modern means of measuring the intensities of spectral lines and then calculating the concentrations of the elements to be determined.

The spectrometer is designed to determine the contents of elements in the range from Na to U in substances in solid, powdery, dissolved states, as well as deposited on the surface or deposited on filters. The principle of operation of the X-ray spectrometer is based on irradiation of the sample with primary radiation from an X-ray tube, measurement of the intensity of secondary fluorescent radiation from the sample at wavelengths corresponding to the elements to be determined, and subsequent calculation of the mass fraction of these elements according to a pre-constructed calibration characteristic, which is the dependence of the content of the element to be determined on the measured intensity. Secondary fluorescent radiation is decomposed into a spectrum using a crystal analyzer. Due to this, the X-ray fluorescence spectrometer has a high resolution, and therefore the ability to accurately analyze complex multicomponent substances.

At the Scientific Research Center of the Russian Academy of Sciences, the technology of acousto-optic filtration of optical radiation is used to create a wide class of optical devices that are successfully used, for example, in biomedicine to diagnose various diseases (including oncology), in agriculture to diagnose the condition of plants, during non-destructive testing of complex technical objects and in solving other tasks. Acousto-optics has a number of important advantages over other technologies for obtaining spectral information: - the ability to create imaging devices without spatial scanning, since the acousto-optic filter is a software-controlled tunable light filter; - the compact modular design allows the acousto-optic filter to be integrated into the optical circuit of most imaging devices, which expands their analytical capabilities; - spectrum scanning is carried out by means of an electrical signal, without mechanical scanning; - fast arbitrary spectral addressing causes high shooting speed and the absence of redundant information; - software management. The key element of the presented device – an acousto–optic filter - is being developed at the Scientific Research Center of the UP RAS on the basis of original calculation methods. The manufacture of acousto-optic filters, optical and mechanical components, as well as the assembly, tuning, and calibration of such devices is also carried out at the Scientific Research Center of the UP RAS.

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.

MAES analyzers for recording atomic emission spectra with a time resolution of 1 ms are based on highly sensitive photodiodes and a special switching board for simultaneous reading of several sections of the spectra. The assembly of the rulers is installed on the "Grand" spectrometer. A " Flow" or twin-jet arc plasmatron is used to excite the atomic emission spectra of powder samples. The ATOM software registers the selected spectral lines and provides their processing according to the specified algorithms, taking into account the number and brightness of flashes (i.e. particle size). Recording the spectra of powder samples with a large time resolution makes it possible to estimate the number and size of individual particles, identify their composition and determine the concentrations of elements in each particle, promptly assess the uniformity of the distribution of certain elements to be determined and expand the possibilities of spectral analysis without significant changes in sample preparation. Main application areas: mass analysis of powder geological samples by scintillation to determine gold, silver, platinum group metals, iridium, rhodium, etc. with detection limits up to 0.01 g/t; qualitative determination of the composition of inclusions and mineral particles.

The wave dispersion sulfur analyzer SPECTROSCAN SW-D3 is designed taking into account all the requirements for the process of X-ray fluorescence elemental analysis of low sulfur contents in petroleum products. The operator's actions when performing measurements are minimized: - the number/name of the sample is entered from the built-in keyboard; - the sample is poured into two cuvettes; - the obtained samples are placed in the analyzer and measurements are started. The analyzer performs all subsequent actions automatically without operator involvement: - calculates and displays the sulfur content in the sample; - calculates convergence - the difference in determining the mass fraction of sulfur in the first and second samples; - prints measurement results on the built-in printer.

The IS-T and IS X-ray absorption flow SPECTROSCAN analyzers for sulfur in oil are designed to determine the mass fraction of sulfur in the flow of oil/petroleum products in the range from 0.02% to 6.00% (IS-T) or 0.04% to 6.0% (IS). Analyzers can be used for technological control during transportation and storage of oil, as well as during mixing (compounding) operations. The design of the analyzers allows them to be placed both independently and as part of a unit for measuring oil quality indicators (BIC) or a system for measuring the quantity and quality of oil (CIC). They are available in explosion-proof version. The analyzers have the function of automatically accounting for the influence of the density of the analyzed medium, as well as the content of water and chloride salts in it on the result of determining the mass fraction of sulfur.
