Application Note: Sulfur Analysis of Petroleum Products by Benchtop WDXRF According to ASTM D2622-10
31 Oct 2012
Sulfur is a critical element in the petroleum refinery process and in its final products. Since sulfur in petroleum-based fuels contributes to atmospheric pollution, its concentration, especially in automobile fuels, must be strictly controlled. This application note demonstrates that sulfur in petroleum products can be routinely analyzed in both low and high sulfur concentration ranges with excellent accuracy, sensitivity and repeatability using a Benchtop WDXRF spectrometer with minimal site requirements. In particular, the Rigaku Supermini200 benchtop WDXRF system, which does not require external water for cooling an X-ray tube or special power supply, meets the specifications of ASTM D2622-10, which has become more stringent in the recent versions of ASTM D2622, which has become more stringent in the recent versions of ASTM D2622.
