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.

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 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.

It is designed for measurement by the method of disturbed total internal reflection with simultaneous visualization of a micro-object on an integrated and external monitor, as well as by the method of mirror-diffuse reflection with an angle of incidence of 45o at the upper location of the sample. The prefix in the mode of a single NIP is used to register absorption spectra: liquids of any degree of viscosity (solutions, suspensions, oils, etc.), including those with high chemical activity; solid objects of arbitrary shape, including samples with very high hardness (any polymers, fragments of paint coatings, etc.); powdery substances, including powders with very high hardness (drugs, pharmaceuticals, explosives, inorganic compounds); samples in the form of thin tapes; samples in the form of fibers. The maximum hardness and chemical resistance of the diamond significantly expand the possibilities of the method; there is no need for periodic replacement of the crystal. The set-top box allows you to register spectra without time–consuming sample preparation, and the presence of a visual inspection system of the studied surface with a high-quality video camera and a built-in high-definition mini-monitor increases efficiency when working with small samples - fragments of thin fibers, microparticles, etc. The built-in monitor has the functions of digital 10X zoom, inverting, etc. The image can be simultaneously displayed on the computer screen (using a USB interface) and then saved as a file. The removable flange provides a quick and convenient sample change and cleaning of the crystal surface. The design with a diamond element protruding above the base plane of the NPVO allows you to study samples with sufficiently large overall dimensions. The high quality and repeatability of the results is achieved due to the absence of the influence of the thickness of the substance layer on the shape of the spectrum and the intensity of the absorption bands. The sample retains its original physicochemical properties and, if necessary, can be further investigated by other methods. The universal attachment clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements. For convenience when working with liquid and paste-like samples, as well as in the ZDO mode, it is possible to rotate the clamping console by 180o. The console is equipped with two replaceable tips – with a spherical working part and with a flat hinged head. The high hardness of the diamond allows the use of large clamping forces, which is the determining factor for obtaining high-quality spectra. A replacement table is used to register the specular and diffuse reflection spectra. The sample is located on the subject plane of the investigated surface downwards. The method is used to determine the spectral characteristics of optical parts, thin tapes on the surface, crystals, and other large solid objects of arbitrary shape and size.

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 main advantage of the PRIZ prefix is the possibility of obtaining well–defined spectra of micro-objects after giving them the shape of a thin layer on mirror-polished metal plates (in the mode of the so-called double passage, when radiation twice penetrates through the layer of matter, reflecting from the mirror-substrate). The presence of a visual control system with a built-in video camera significantly increases the information content when setting up and the reliability of the results obtained. With the help of the prefix, it is also possible to register the reflection spectra of bulk samples and solid objects of arbitrary geometry in native form, including pharmaceuticals in the form of tablets, powders and granules, polymer fragments, LCP, films deposited on the surface.

Atomic Emission Complex "Grand Globula" includes a spectrometer "Grand", a spectroanalytic generator "Ball Lightning" and a tripod "Globula". It allows the analysis of various substances and materials in arc and spark discharges in air, for example according to GOST 17818.15-90 "Graphite. Spectral analysis method", GOST 9717.1-82 "Copper. A method of spectral analysis based on metallic standard samples with photoelectric spectrum registration" and other MVIS.

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 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. Structurally, the analyzers are a complete product of high factory readiness, having a block-modular design and including all the necessary functional devices to ensure efficient and safe operation.
