The spectrometer is designed to determine the contents of elements in the range from Ca 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 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 being 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 being determined on the measured intensity. Secondary fluorescent radiation is decomposed into a spectrum using a crystal analyzer. Due to this, the spectrometer has a high resolution, and therefore the ability to accurately analyze complex multicomponent substances.

Diesel engine oil spectrometric analysis system "EXPRESS-OIL" is designed to analyze engine oils according to GOST 20759 and determine the concentration of wear elements of rubbing diesel parts, contaminants and additives in diesel engine oils during scheduled maintenance and repair of traction rolling stock in locomotive repair depots, as well as electronic accounting and analysis of dynamics data the content of wear elements in engine oils for each locomotive, as well as the determination of the composition of metals and alloys according to GOST, greases (according to CTCH-28/4, CTCHS-53) and other materials.

The laser source is designed to excite atomic emission spectra when performing qualitative spectral analysis of hard rocks - metals, minerals, glasses and others. The source is based on a two-pulse YAG: Nd laser with electro-optic Q-switching operating at the main wavelength of 1064 nm. The duration of each pulse is no more than 10 ns, and the delay between them is adjustable from 0 to 60 microseconds. The possibility of the laser beam to focus on an area of 300 to 1000 microns makes it possible to conduct microanalysis of inclusions, perform two-dimensional scanning of the surface or locally analyze samples with virtually no damage to the surface. A significant advantage of the laser source is the expressiveness and lack of special sample preparation for a wide range of conductive and non-conductive materials. Visual observation and pointing of the beam at the sample is carried out using a stereoscopic microscope integrated into the system, as well as a high-resolution digital video camera with image transmission to a computer. Moving the instrument table with a fixed sample is possible both manually for adjustment, and with the help of stepper motors in two coordinates during analysis, which provides surface scanning and spectrum recording with reference to the video image. The installation can be used in conjunction with any spectral devices – "Grand", "Aspect", "Express", "Hummingbird-2", STE-1, DFS-458, MFS-8, PGS-2 and others. The laser source is designed to excite atomic emission spectra when performing high-quality spectral analysis of hard rocks – metals, minerals, glasses and others.

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. All manufactured devices undergo primary verification and have the appropriate certificate. Analyzes a wide range of quality indicators (protein, moisture, quantity and quality of gluten (IDC), fat/oil content, water absorption capacity, acid number, peroxide number, m.d. phosphorizing substances, etc.) Is calibrated to assess moisture and protein in whole grains (wheat, barley). The cuvette compartment for the analysis of bulk, liquid and pasty products allows to analyse liquid vegetable oils without the use of additional devices. The built-in whiteness module allows to determine the whiteness of the product simultaneously with other quality indicators (moisture, protein, amount of gluten). A wide spectral range (400-2500nm) provides measurement of the zonal reflection coefficient to determine the whiteness of flour in accordance with the GOST 26361-2013 methodology. It is possible to calculate the amino acid composition of feed components. To organize the work of analyzers in the ECANET network, the INFRASCAN-4200 analyzer can be used as a server for storing and transmitting data. The remote access mode allows to remotely update existing calibrations, install additional calibration models and develop new calibration models for new products, as well as make adjustments to technical settings if necessary.

The MS-1104E spectrometer is characterized by high performance and accuracy of Mössbauer measurements achieved through the use of “compressed” geometry, as well as the use of highly efficient and selective resonant scintillation detection units that improve the energy resolution of resonance absorption lines by up to 30%. The technique of software and hardware stabilization of the spectrometric path developed and used in the spectrometer allows for long-term Mossbauer measurements without manual adjustment. The method of modulation in the specified speed intervals can significantly increase the sensitivity and expressiveness of measurements and reduce the time to determine the magnitude of the effects of resonant absorption by tens of times in the study of temperature phase transitions with a low concentration of resonant elements. The electronic components of the spectrometer are developed on the basis of a modern element base using programmable logic matrices and microprocessors. Adjustable spectrometric paths and high-voltage power supplies of the PMU are integrated into detection units, modulator driver modules and multi-channel storage are made in the ISA standard and are located in the processor unit of the computer. Setting and monitoring of all parameters of the spectrometer and processing of the measured spectra is carried out from the operating windows of the control and processing programs. Since 2000, more than ten spectrometers of this type have been supplied to leading scientific organizations in Russia and neighboring countries. One of the few industrial applications of Mössbauer spectroscopy should be noted - the development and supply to the Volgodonsk NPP of certified MS-1104Em methods and spectrometer for monitoring corrosion processes in the heat exchange circuits of the VVER-1000 reactor.
