NT-MDT S.I. presents NTEGRA II, the second generation of the world's most popular AFM. Thanks to additional features and advanced functions, it provides an unprecedented level of modularity and flexibility, becoming a true partner of the researcher. Intelligent, fast, reliable, accurate and undoubtedly easy to use. To eliminate the influence of a noisy environment, the NTEGRA II is supplied in a standard cabinet that provides temperature control, acoustic and vibration isolation. This combination reveals the true nature of NTEGRA II as the most stable AFM in the world, providing a temperature drift of less than 0.2 nm/min.

NT-MDT Spectrum Instruments is an INTEGRA Nano IR–scattering scanning near‑field optical microscope (s-NSOM) designed for the infrared spectral range. The AFM probe is located in the focus of an optical system that directs the IR laser radiation to the sample and collects the optical response. The collected radiation is sent to the Michelson interferometer for optical analysis. The far-field component of the collected signal is suppressed by synchronous detection. The INTEGRA Nano IR system allows detecting the amplitude and phase of the near-field signal. The spatial resolution of the resulting reflection and absorption contrasts is approximately 10 nm and is determined only by the size of the tip of the probe.

The system includes a digital ionization-thermocouple vacuum meter with a continuous pressure measurement range, automatic degassing of sensors and a digital gas flow meter containing two or more built-in precision gas flow regulators, with thermometric gas flow meters, which allows the device to operate in the mode of autonomous intake of specified gas flow rates, regardless of the inlet pressure. The letters in the diagram show: А — electronic unit of vacuum gauge B — 220V power wire С — thermocouple lamp D — ionization lamp E — the electronic control unit of the leak valve G — signal cables H — cable for data exchange with IBM J — IBM L — cable for data exchange between the units M — cable for connecting additional devices to the network N,O — working gases inlet P,R — output of the working gases.

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)

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 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:1.8—1000 m3/h Purity: 90-99,99 % 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 IR microscope "MIKRAN" is designed to work with IR Fourier spectrometers "Infralum FT-801". The spectral range is 6000 – 600 cm-1 (with a microscope and an MST detector cooled with liquid nitrogen). Resolution 0.5, 1, 2, 4, 8 cm-1 (determined by the resolution of the Fourier spectrometer)

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.
