Elements Analyzer by WDXRF

KN-2622 Elements Analyzer by WDXRF

Overview

  KN-2622 Elements Analyzer by WDXRF conforms to ASTM D2622 Standard Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-ray Fluorescence Spectrometry, ASTM D7039 Standard Test Method for Sulfur in Gasoline, Diesel Fuel, Jet Fuel, Kerosine, Biodiesel, Biodiesel Blends, and Gasoline-Ethanol Blends by Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry and ASTM D7536 Standard Test Method for Chlorine in Aromatics by Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry. The sample is placed in the X-ray beam, and the peak intensity of the sulfur Kα lineat 0.5373 nm is measured. The background intensity, measured at a recommended wavelength of 0.5190nm (0.5437nm for a Rh target tube) is subtracted from the peak intensity. The resultant net counting rate is then compared to a previously prepared calibration curve or equation to obtain the concentration of sulfur in mg/kg or mass %.
