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.

To achieve the maximum sensitivity during measurements, a special prefix is used to the FT-801 Fourier spectrometer, which is an optical unit with a built-in highly sensitive MST detector cooled with liquid nitrogen. The set-top box is installed in the cuvette compartment of the spectrometer and connected to the corresponding external electrical port, the detector is turned on programmatically. In this case, the sensitivity of the method increases many times (up to 20) – depending on the type of standard uncooled detector in the spectrometer). The speed of recording spectra is also increasing. The operating time after filling the cryostat (200 ml capacity) with liquid nitrogen is at least 6 hours. Increasing the sensitivity of the spectrometer using a prefix with an MST detector may be required for many applications: in fiber spectroscopy, when recording emission spectra of low-power emitters, in trace gas analysis with high spectral resolution, when determining the presence of impurities in samples in ultra-low concentrations, when using multi-pass gas cuvettes, etc. In the picture: on the left in the cuvette compartment there is a capler with fiber from Art photonics GmbH, Berlin, Germany, on the right there is a prefix with an MST detector. Technical specifications The recommended number of scans when registering spectra is 16 Spectrum registration time at 50 scans (resolution 4 cm-1), sec 20 Cryostat capacity, 200 ml Working time after filling the cryostat, 6 hours Overall dimensions, mm 225×175×75 Weight, kg 1.45

A remote-controlled atomizer of powder samples with automatic change of revolver-type samples with arc excitation of the spectrum. It consists of an automatic tripod "Carousel" for arc spectral analysis and a spectroanalytic generator "Ball Lightning"– 40A fully compatible with the expert software system "ATOM" and the MAES analyzer.

The generator is designed to produce an electric arc and spark discharge in atomic emission spectral analysis installations. The generator is designed specifically for use in spectral analysis of samples of complex composition for simultaneous determination of impurity and alloying components in a wide range of concentrations.

A liquid flask with an adjustable layer thickness of the liquid under study is made in the form of an optical-mechanical attachment installed in the cuvette compartment of the FT-801 spectrometer. It contains focusing optics, removable holders of two windows-substrates with a diameter of 10 mm and two adjusting screws placed on the upper panel of the console housing and designed to set the required gap between the windows. A liquid of any degree of viscosity is pre-applied in the form of a small drop to the lower window and then, in the process of smooth convergence of the windows, evenly fills the gap between them. By rotating the adjusting screws and observing the transmission spectrum online, the user has the opportunity to set the desired thickness of the liquid layer, guided by the overall intensity of the entire spectrum or by the intensity of specific absorption bands. In the presence of calibration, which is easy to create using the ZaIR 3.5 program for several samples with a known concentration, the cuvette allows quantitative measurements. The flask is indispensable in the analysis of mixtures containing impurities in small proportions. Technical specifications Transmission in the operating range of the spectrum, % of the input signal at least 50 The recommended number of scans when registering spectra is 16 Time of spectrum registration at 16 scans (resolution 4 cm-1), sec 20 Minimum volume of the studied liquid, mm3 1 The diameter of the focus spot, mm 3 Overall dimensions, mm 200×90×160 Weight, kg 1,1 The figure shows several spectra of the viscous lubricant "Buxol", illustrating the process of selecting the thickness of the sample layer between the windows. The measurement process has a high expressiveness and reproducibility, inexpensive replaceable substrate windows are used, the system is easy to configure and clean, a very small amount of sample is required to obtain high-quality spectra.

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. Technical specifications Transmission in the operating range of the spectrum, % of the input signal at least 40 The recommended number of scans when registering spectra is 25 Spectrum registration time at 25 scans (resolution 4 cm-1), sec 30 Minimum initial dimensions of a solid sample, mm 0.2 × 0.2 The maximum area of the solid sample, mm 20X20X10 Variable focus range, mm 10 The diameter of the focus spot, mm 3 The angle of incidence of radiation (central beam) on the sample in the ZDO 45o mode Micro lens magnification / total magnification of the 4X visual channel Field of view of the optical system, mm 2 X 2.5 The resolution of the digital video camera is 640x480 Overall dimensions, mm 140×105×160 Weight, kg 1.16

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.
