D2622-Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-ray Fluorescence Spectrometry

The precision of ASTM D2622 was determined by the statistical analysis of results obtained from an interlaboratory study that included 27 samples including gasolines, distillates, biodiesel, residual oils, and crude oils. A pooled limit of quantitation (PLOQ) of approximately 3 mg/kg S, was determined for all sample types. Precision for gasoline and diesel samples, as well as for high- power and low-power source XRF instruments were also determined.
