A monochromatic X-ray beam with a wavelength suitable to excite the K-shell electrons of sulfur is focused onto a test specimen contained in a sample cell. The fluorescent Kα radiation at 0.5373 nm (5.373 Å) emitted by sulfur is collected by a fixed monochromator (analyzer). The intensity (counts per second) of the sulfur X rays is measured using a suitable detector and converted to the concentration of sulfur (mg/kg) in a test specimen using a calibration equation.
Petrochemical products such as gasoline, diesel, blending distillate, jet fuel, kerosene, biodiesel, Biodiesel Blended fuel, ethanol gasoline, heavy oil, etc. It is suitable for petrochemical enterprises, refining, quality inspection departments, third-party testing and other industries.
