The device is developed on the basis of the analyzer SPECTROSCAN SW-D3, allows you to determine the mass fraction of organochlorine compounds in oil according to GOST R 52247-2004 (method B) and GOST 33342-2015 (method B), the sulfur content in automotive fuel, oil and liquid petroleum products in accordance with GOST R 52660-2006 / GOST ISO 20884-2016 and GOST R 53203-2008 / GOST 33194-2014, as well as to determine the mass fraction of chlorine and sulfur in any liquid samples in accordance with standardized techniques (methods). Implements arbitration methods for determining the mass fraction of organochlorine compounds in oil and the sulfur content in automobile fuel. The analyzer has successfully passed the interlaboratory tests under the guidance of JSC "VNII NP" (TK31). As a result of the tests, the accuracy of the method for determining the mass fraction of organochlorine compounds using the SPECTROSCAN CLSW analyzer was found to comply with the requirements of GOST R 52247-2004, method B, and the accuracy of the method was determined in the range of the mass fraction of organochlorine compounds from 1 ppm to 50 ppm. Determination of the mass fraction of organochlorine compounds in oil involves sampling of oil, distillation of naphtha fraction (204 ° C), washing of naphtha from hydrogen sulfide and inorganic chlorides. An internal standard is introduced into naphtha extracted from oil – a solution of bismuth in a non-polar solvent and an analysis is carried out. When determining the sulfur content, the analysis is carried out without additional sample preparation. 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 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 chlorine and/or sulfur content in the sample; - calculates convergence - the difference in determining the mass fraction of an element in the first and second samples; - prints measurement results on the built-in printer.
