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.

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 wide-range IR microscope of the MICRAN series, connected to the FT-801 and Infralum FT-801 Fourier spectrometers, is designed to study samples from 10 microns in size, including heterogeneous in composition. When working on an IR microscope, the operator has the opportunity to observe the object under study with a magnification of over 200X both using binoculars and on a monitor using a digital video camera, during photometry, select a local area of arbitrary shape with the help of diaphragms, and also “scan” the surface of the sample, observing the spectrum obtained in real time.

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.

A remote-controlled atomizer of powder samples with automatic change of revolver-type samples with arc excitation of the spectrum.

It is designed for recording absorption spectra of solid, liquid and gaseous substances in the near and middle IR region (including drugs, lacquers and paints, petroleum products, explosives, pharmacological preparations, polymer films and fibers) with their subsequent identification, as well as for qualitative and quantitative analysis of mixtures containing several components.

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.
