Specialized wavelength-dispersive XRF analyzer based on the Cochois scheme is designed for high-precision determination of chemical elements U, Th, Mo, Au, W, Tl, As, Pb as well as other elements in ores, rocks and when developing the technogenic fields. Possibility to determine groups of elements without readjustment of crystal-analyzer. Exceptionally high resolution of the Koshua X-ray optical scheme with crystal-analyzer quartz 1011. Developed mathematical support. Principle of analyzer operation is based on the excitation of the fluorescent radiation of sample atoms being under examination by radiation coming from an X-ray tube. 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.

The analyzer is designed to determine the mass fraction of sulfur in automotive fuel in accordance with GOST R 52660-2006 / GOST ISO 20884-2016, ASTM D6334, as well as in oil and petroleum products according to GOST R 53203-2008 / GOST 33194-2014, ASTM D2622, GB/T 11140-2008. 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.

The analyzer allows you to determine the content of sulfur and nitrogen in oil and petroleum products (diesel fuel, gasoline, kerosene, gas oil and any distillate petroleum products), hydrocarbon gas, liquefied petroleum gas (LPG), natural gas, liquefied natural gas (LNG), chemical synthesis products, biological materials by ultraviolet fluorescence and chemiluminescence. The analyzer is a proprietary development of NPO "SPEKTRON". The device is manufactured in St. Petersburg mainly from domestic components. There is a conclusion of the Ministry of Industry and Trade on the production of products in the territory of the Russian Federation. The analyzer is designed to determine: - mass fraction of sulfur in accordance with GOST ISO 20846-2016, GOST 34712-2021, GOST R 56866-2016, GOST 34237-2017, ASTM D5453-19, ASTM D6667-21, ASTM D7551-15, ISO 20729-17 ; - the mass fraction of nitrogen in accordance with ASTM D4629-17. A wide range of concentrations: from ultra-low to high. Modular principle: Each detector is a separate module. The device is equipped individually for each specific task. The possibility of simultaneous determination of sulfur and nitrogen in the analysis process. The principle of operation of the analyzer is to burn the test sample in an oxygen-enriched atmosphere or air at a temperature of 1050 ° C. The sulfur dioxide (SO2) and nitrogen oxide (NO) formed during combustion are transferred by carrier gas to the detection units with preliminary removal of water vapor, on the desiccant, and soot, on the filter. Determination of sulfur is carried out by ultraviolet fluorescence. Determination of nitrogen by chemiluminescence.
