It is used in the study of samples compressed into small-diameter tablets with KBr (the method is convenient for spectral analysis of powdery substances - the prefix allows you to work with small amounts of the sample using a manual press for the manufacture of tablets). • The diameter of the focus spot is less than 3 mm • Parabolic mirror optics are used in the design • Windows-substrates can be placed in the prefix after pasty, liquid substances or extracts are applied to them, followed by drying of the layers • Limited use – in the study of whole samples with dimensions less than 5 mm (preferably using a vertical-type microfocusing attachment)

The 2ZVE-250R vacuum shutter with electromechanical drive equipped with 250mm conditional passages is designed to overlap vacuum systems in the range of operating pressures from 1x10-6 to 1.07x105 Pa (0.75x10–8 to 800 mm Hg). The 2ZVE-250R shutter is pendulum-type. The 23VE-250R shutter is manufactured in the climatic version UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69. The working environment is air and non–aggressive gases. It is not intended for use in fire and explosive hazardous industries. The 23VE-250R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, the gate belongs to Class I electrical equipment according to GOST 12.2.007.0-75.

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.

It is intended for sample preparation when examining samples using an IR microscope and mirror reflection prefixes. Allows you to shape a thin layer (up to several microns) to various objects: polymer fragments, microparticles of LCP, powdery substances, fibers, etc. The resulting thin layers on mirror plates made of alloy steel are investigated by the double transmission method – when the radiation that has passed through the layer of matter is reflected from the surface of the plate and passes through the substance again. The spectra recorded by this method are completely identical to the transmission spectra obtained, for example, after pressing substances with KBr. The advantages in this case are: - speed of sample preparation - there is no need to use hydraulic and manual presses and molds, grinding mortars, etc. - no need to use high-purity KBr or petroleum jelly oil - the sample is not lost and, if necessary, can be examined by other methods - when using an IR microscope, it is possible to “scan” the resulting thin layer to select the most informative area, and also, if the layer is heterogeneous in composition, to obtain the spectral characteristics of its components.
