EDXRF Application Note: Sulfur and Chlorine in Crude Oil

1 Aug 2013

This application note highlights the NEX QC+ EDXRF as a simple yet powerful and versatile system for quantifying elemental composition using the empirical approach. Results demonstrate that the NEX QC+ EDXRF can achieve excellent results in screening and monitoring the concentration of sulfur, chlorine and other elements in crude oil and other similar oils.

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. Find the best XRD and XRF spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Crude OilThe chemical evaluation of the complex combination of hydrocarbons and organometallic compounds found within crude oil. The results provide data on the chemical characteristics of a sample for petroleum testing laboratories.Oil and Grease
