The M532® Raman microscope combines the capabilities of the Inspectr R532® Portable Raman Express Analyzer and the U300M microscope, adapting it for both transmission and reflection measurements. The wide functionality of the M532 microscope makes it possible to find and analyze individual particles with a size of 2-3 µm among many similar ones with similar physical and chemical properties, which opens up new research opportunities within the framework of a single Raman system. A spatial resolution of 1 µm and a spectral resolution of 4-6 cm-1 ensure excellent measurement accuracy and reproducibility. The compact design and portability of the instrument allow for high-quality and instant analysis of substances without sample preparation, which makes the M532 microscope an indispensable instrument for a wide range of studies. Equipped with a motorized slide (optional) with a step of 0.36 µm, the M532 microscope scans the surface of the sample, recognizes substances in multi-component heterogeneous mixtures and creates a graphical image of the intensities of Raman scattering characteristic lines at various points on the surface (2D mapping), which makes the M532 microscope the most advantageous in terms of price-quality ratio scanning Raman microscope in the world market.

A membrane nitrogen generator is a special equipment designed to produce gaseous nitrogen from atmospheric air by the method of membrane separation. The gas separation process proceeds due to the different penetration rates of the components of the gas mixture through the polymer membranes due to the differential partial pressures on both sides. During the separation of compressed air, impenetrable nitrogen passes along the entire length of the membrane module and enters the consumer, and oxygen, which has better permeability through the membrane, is discharged into the atmosphere as permeate. At the output, we get a gas mixture with a nitrogen content of up to 99.9%. The main components of the membrane generator are: membrane modules placed on a support frame-base together with auxiliary components (valves, regulators), respectively connected to each other. The generator is equipped with an automatic control system to control the parameters of the gas mixture separation process.

Provita Company designs and manufactures mobile nitrogen stations based on sea containers (10, 20, 30, 40–feet) and sandwich panel block boxes with standard dimensions and fasteners, which allows stations to be transported by road, rail and sea transport. The Provita company also produces installations on automobile chassis or on sleds for transporting stations to remote hard-to-reach regions. Mobile nitrogen modular stations can be supplied in various climatic versions: northern (ambient temperature up to -55°C) standard (ambient temperature from -45 to +45°C) tropical (ambient temperature up to +55°C)

Adsorption nitrogen plant is a set of equipment for the production of nitrogen from atmospheric air by short–cycle heat-free adsorption at a pressure of up to 13 bar. The adsorption nitrogen plants of the Provita company allow to produce nitrogen with a purity of up to 99.9999%. The capacity of the plants ranges from several liters per minute to hundreds of cubic meters per hour. The basis of the installations are nitrogen adsorption generators developed and manufactured by our company. A carbon molecular sieve with a developed microporous structure is used as an adsorbent. The gas generator requires dry compressed air with a pressure of at least 6 bar to operate, so the installation includes an air compressor, as well as a dehumidifier and an air receiver (if they are not part of the compressor). The source air must be cleaned of dust and oil, which is carried out by the main filters included in the installation or directly by the nitrogen generator. The nitrogen receiver is used for the accumulation of production gas.

The nitrogen adsorption generator is a special equipment designed to produce nitrogen gas from atmospheric air by the method of short-cycle non-heating adsorption. Capacity:300-10000 m3/h Purity: 90-99.9999 % Pressure: 4-450 bar

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.

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 spectrometer is designed to measure the intensities of analytical lines of chemical elements and, by recalculating them, determine the mass concentration of elements from P(15) to U(92) contained in the analyzed sample. The process of analysis from a set of data and their processing to obtaining results in the form of a table of concentrations of the elements being determined is automated and performed using a personal computer. The spectrometer can be used in various fields of science and technology (ecology, biology, medicine, agriculture, food industry, geology, mining, geophysics, sanitary and epidemiological control, etc.).

NTEGRA Spectra II is already a second-generation measuring system that successfully demonstrates the unification of two worlds: AFM and Raman spectroscopy. It can perform multiple functions ranging from relief mapping to 2D spectral analysis, from studies of electrical and mechanical properties to optical measurements with a resolution below the diffraction limit. Now scientists can conduct a complete physico-chemical analysis of the surface properties of the sample at a time. As a result, researchers get unlimited opportunities to develop their laboratory techniques.

Designed for monitoring processes in reactors, vacuum chambers, gas pipelines, etc.

The advantage of the system using a closed-cycle helium cooling unit from Helix Technology Corporation (USA) is the ability to provide low measurement temperatures (up to 10 K) without loss of consumables (helium) with a compact arrangement of equipment. Isolation of the studied absorber from vibration associated with the operation of the compressor is ensured by ensuring heat exchange of the absorber with the cooling head of the unit through an intermediate layer of helium gas and by careful vibration isolation of the systems of the Mossbauer spectrometer, minimizing additional broadening of the spectrum lines during operation of the cooling unit. All modes and characteristics of the MS-1104Em Mossbauer spectrometer are preserved at the same time.
