Depending on the customer's needs, the analyzer is configured to work in accordance with a particular standard.
Implements an arbitration method for measuring the mass fraction of sulfur in automobile fuel of the third, fourth and fifth classes.
The device is designed specifically for high-quality and fast X-ray fluorescence analysis of fuel in accordance with the technical regulations "On requirements for automotive and aviation gasoline, diesel and marine fuel, jet fuel and heating oil", which establishes an arbitration X-ray fluorescence wave dispersion method for determining the mass fraction of sulfur in automotive fuels of the third, fourth and fifth classes.
The wave dispersion sulfur analyzer SPECTROSCAN SW-D3 is designed taking into account all the requirements for the process of X-ray fluorescence elemental analysis of low sulfur contents in petroleum products. The operator's actions when performing measurements are minimized:
- the number/name of the sample is entered from the built-in keyboard;
- the sample is poured into two cuvettes;
- the obtained samples are placed in the analyzer and measurements are started.
The analyzer performs all subsequent actions automatically without operator involvement:
- calculates and displays the sulfur content in the sample;
- calculates convergence - the difference in determining the mass fraction of sulfur in the first and second samples;
- prints measurement results on the built-in printer.

Spectrometer SPECTROSCAN MAX-GVM
The spectrometer is designed to determine the contents of elements in the range from Na to U in substances in solid, powdery, dissolved states, as well as deposited on the surface or deposited on filters.
The principle of operation of the X-ray spectrometer is based on irradiation of the sample with primary radiation from an X-ray tube, measurement of the intensity of secondary fluorescent radiation from the sample at wavelengths corresponding to the elements to be determined, and subsequent calculation of the mass fraction of these elements according to a pre-constructed calibration characteristic, which is the dependence of the content of the element to be determined on the measured intensity.
Secondary fluorescent radiation is decomposed into a spectrum using a crystal analyzer. Due to this, the X-ray fluorescence spectrometer has a high resolution, and therefore the ability to accurately analyze complex multicomponent substances.

Spectrum decomposition of the fluorescence radiation is performed according to Cauchois method. The fluorescence radiation focused by analyzing crystal and standard line are marked on Rowland focal circle. Then, they are recorded by X-ray radiation detector in turn. The intensity of the fluorescent irradiation with a particular wavelength is directly proportional to the chemical element concentration in the material under examination.

MAX-GF1(2)E-C Spectrometer
The X-ray fluorescence spectrometer SPECTROSCAN MAX-GF1(2)E-C combines two methods of detecting an analytical signal: diffraction on a crystal (wave dispersion - WDX) and energy dispersion (EDX) method, as well as sample delivery adapted for the analysis of large-size images. The collimation of the primary radiation of the X-ray tube and the special design of the sample presentation make it possible to analyze the sample over an area of 1 cm2 in 1 mm increments, and thus investigate the distribution of elements over an area.
The spectrometer is designed to determine the contents of elements in the range from Ca to U in substances in solid, powdery, dissolved states, as well as deposited on the surface or deposited on filters. With the help of fixed energy dispersion channels, any one or two additional elements in the range from magnesium (Mg) to calcium (Ca) can be determined.
With the help of this modification of the spectrometer, forensic and customs examinations, judicial and forensic medical examinations, as well as art-historical examinations are carried out.

Energy dispersive sulfur-in-oil analyzer ASE-2
The ASE-2 energy dispersive sulfur analyzer is designed to measure the mass fraction of sulfur in unleaded gasoline, diesel fuel, crude oil, kerosene, oil residues, lubricating oil bases, hydraulic oils, jet fuels and other distillate oil products.
X-ray radiation from a low-power X-ray tube, converted by a primary radiation filter, excites fluorescence emission from the atoms of the sample being analyzed. The fluxes (primary X-rays scattered on the sample and secondary fluorescence) of radiation fall on a gas proportional counter, whereby the fluorescence radiation of sulfur atoms (SKa) is separated from the radiation with other energies by means of selective filters. The intensity of the fluorescence emission of sulfur atoms registered by the gas proportional counter is proportional to the mass fraction of sulfur in the analyzed sample.

The principle of operation is based on the excited fluorescence produced by the atoms of the material under analysis through the radiation of an X-ray tube. The fluorescence radiation of a particular chemical element is picked up by the crystal analyzer, and then the radiation at a specific wavelength is detected by an X-ray tube detector. The intensity of the recorded fluorescence radiation of a certain wavelength is directly proportional to the mass fraction of the chemical element in the substance under study.

Small-sized multichannel spectrometer - "Hummingbird-2"
The spectrometer was created according to the Cherni-Turner scheme based on a flat diffraction grating and an MAES analyzer with one line of photodetectors. It has increased photometric accuracy due to cooling and temperature stabilization of the photodetector range, as well as due to its shell-less design, in which there is no re-reflection of radiation on the cover glass and the background level in the recorded spectrum decreases. The optical scheme and design of the spectrometer are optimized to obtain a high-quality spectrum with a low level of background radiation in any of the regions lying in the spectral range of 190-1100 nm. The choice of the working area is carried out by changing and rotating the diffraction gratings. The sealed case of the spectrometer is filled with an inert gas. The radiation is injected into the spectrometer using a quartz capacitor or a fiber-optic cable with an SMA-905 connector. The optical scheme and design of the spectrometer are protected by patents.
