Analysis of Low Concentration Sulfur in Petroleum-based Fuels by WDXRF According to ASTM D2622-10
4 Jan 2013Sulfur in petroleum-based fuels contributes to atmospheric pollution. X-ray fluorescence (XRF) spectrometry has been used for quantitative analysis of sulfur in petroleum-based fuels, owing to simple sample preparation. This application note demonstrates quantitative analysis of low concentration sulfur in diesel fuel, gasoline and kerosene according to ASTM D2622-10 on Rigaku ZSX Primus, a wavelength dispersive X-ray fluorescence (WDXRF) spectrometer.

X-Ray Diffraction and SpectroscopyX-Ray diffraction & spectroscopy are used in material characterization to discern the structure and elemental composition of a sample. X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography.
