Designed for the preparation of samples in the form of compressed tablets with a diameter of 3.5 mm, consisting of the test substance in a mixture with microcrystalline potassium bromide (KBr). - the principle of operation of the device is based on creating the pressure necessary for pressing due to a mechanical lever system - the press is made of high-quality alloy hardened steel - for the manufacture of a tablet with a diameter of 3.5 mm, a minimum amount of the test substance and KBr is required - for the study of finished samples on a Fourier spectrometer, a vertical or horizontal microfocusing prefix is used

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.

MAES analyzers for recording atomic emission spectra with a time resolution of 1 ms are based on highly sensitive photodiodes and a special switching board for simultaneous reading of several sections of the spectra. The assembly of the rulers is installed on the "Grand" spectrometer. A " Flow" or twin-jet arc plasmatron is used to excite the atomic emission spectra of powder samples. The ATOM software registers the selected spectral lines and provides their processing according to the specified algorithms, taking into account the number and brightness of flashes (i.e. particle size). Recording the spectra of powder samples with a large time resolution makes it possible to estimate the number and size of individual particles, identify their composition and determine the concentrations of elements in each particle, promptly assess the uniformity of the distribution of certain elements to be determined and expand the possibilities of spectral analysis without significant changes in sample preparation. Main application areas: mass analysis of powder geological samples by scintillation to determine gold, silver, platinum group metals, iridium, rhodium, etc. with detection limits up to 0.01 g/t; qualitative determination of the composition of inclusions and mineral particles.

The video camera and servos of the electrode holders built into the tripod are designed to automatically maintain the interelectrode gap during the evaporation of the sample by computer analysis in real time of the image of the arc discharge, as well as the initial setting of this gap relative to the optical axis. The electrode holders are cooled with water using a closed-cycle cooling unit.

A device for preparing metal samples for spectral analysis. For the preparation of metal samples, an emery cloth or paper with a given size and abrasive material is used. The rotation speed is 1500 revolutions per minute. A quick stop of the motor is provided by an automatic control unit. There is a version in a housing made of composite materials with two discs, each can have its own type of abrasive.

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.
