Analysis of Low Concentration Sulfur in Automotive Fuels by Mini-Z Sulfur Analyzer According to ASTM D2622-10
4 Mar 2013Low concentration sulfur in petroleum-based fuel can be routinely analyzed with high accuracy and precision on the Mini-Z Sulfur Analyzer, a benchtop single fixed-channel WDXRF spectrometer, which does not require external water for cooling an X-ray tube or special power supply. This application note demonstrates that the performance of the Mini-Z Sulfur Analyzer meets the requirement of ASTM D2622-10, which has become strict in the recent versions of ASTM D2622.

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.
