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 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 AP-35 analyzer is a fully automated analytical complex designed for continuous X-ray fluorescence analysis of the chemical composition of slurries and solutions in flow. The instrument has a movable software-controlled measuring head with an X-ray tube and fixed spectrometric channels (up to 8), each of which can be set up for any chemical element (from Ca to U). In operation, up to 15 flow cells are measured by the head according to a preset program. Multi channel capability (up to 15 products to be measured). Compatibility with automation systems for sampling, sample delivery, data handling and presentation, data archiving. Link to factory process control system High expressiveness, high analytical precision, low detection limits, reproducibility High reliability. The principle of operation is based on the excited fluorescence produced by the atoms of the material under analysis through the radiation of an X-ray tube. The fluorescence radiation of a particular chemical element is picked up by the crystal analyzer, and then the radiation at a specific wavelength is detected by an X-ray tube detector. The intensity of the recorded fluorescence radiation of a certain wavelength is directly proportional to the mass fraction of the chemical element in the substance under study.

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 video camera and servos of the electrode holders built into the tripod are designed to automatically maintain the interelectrode gap during the evaporation of the sample by computer analysis in real time of the image of the arc discharge, as well as the initial setting of this gap relative to the optical axis. The electrode holders are cooled with water using a closed-cycle cooling unit.

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.

The main advantage of a mobile spectrometer is the ability to measure the composition of alloys not only in the laboratory on specially prepared samples, but also directly in a workshop or warehouse without cutting the product or workpiece.
