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.

The MAES analyzer is a modern means of measuring the intensities of spectral lines and then calculating the concentrations of the elements to be determined.

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.

Designed for the preparation of samples in the form of compressed tablets with a diameter of up to 13 mm, consisting of the test substance in a mixture with microcrystalline potassium bromide (KBr). - the principle of operation of the press is based on the injection of pressure in the hydraulic system by swinging the lever. - to control the working pressure, the press is equipped with a pressure gauge - complete with a press, molds with a diameter of 13 mm and 3.5 mm can be used - for the study of finished samples on a Fourier spectrometer, a KBr tablet holder and D13mm substrate windows or a microfocusing attachment (for 3.5 mm tablets) is used

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

Atomic Emission Complex "Grand Globula" includes a spectrometer "Grand", a spectroanalytic generator "Ball Lightning" and a tripod "Globula". It allows the analysis of various substances and materials in arc and spark discharges in air, for example according to GOST 17818.15-90 "Graphite. Spectral analysis method", GOST 9717.1-82 "Copper. A method of spectral analysis based on metallic standard samples with photoelectric spectrum registration" and other MVIS.

The plasmatron is designed for direct atomic emission spectral analysis of powder samples. The excitation of atoms occurs in a DC argon arc plasma. Weak matrix effects and low detection limits make it possible to use this excitation source for the analysis of various samples, both with mineral and organic matrix.

The installation is designed to excite atomic emission spectra of powder samples in an electric arc by the spillage-injection method. It provides high performance of routine analyses, has a low consumption of graphite electrodes and is used in conjunction with any spectral devices – "Grand", STE-1, DFS-458, MFS-8, PGS-2, etc.

Vacuum spectrometers are designed for rapid analysis of alloys based on iron, copper, aluminum and other metals in factory and research laboratories, including the determination of elements having analytical lines in the field of vacuum ultraviolet (VUV) (for example, S, P and C in steels).
