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.
