Applied Rigaku Technologies, Inc. is pleased to publish a new application report which details the measurement of sulfur in ultra-low sulfur diesel (ULSD) using the Rigaku NEX CG EDXRF analyzer. The performance complies with ASTM D7220-12, Standard Test Method for Sulfur in Automotive, Heating, and Jet Fuels by Monochromatic Energy Dispersive X-ray Fluorescence Spectrometry (EDXRF).

The Scope of D7220-12 shows a Pooled Limit of Quantification (PLOQ) of 3 mg/kg sulfur, indicating the use of monochromatic EDXRF for the determination of sulfur over the concentration range of 3 to 942 mg/kg. This test method is applicable to gasoline, oxygen enriched gasoline (RFG), diesel, diesel/biodiesel blends containing up to twenty volume percent biodiesel, kerosene, jet fuel, jet fuel/biodiesel blends containing up to five volume percent biodiesel and No. 2 home heating oil.

The Rigaku results demonstrate the superior performance of the NEX CG analyzer for the measurement of ULSD for control and certification of 10-15 ppm S at the pump, as well as lower levels controlled at the refinery, pipeline or tank farm. The NEX CG also complies with IP 352 for ULSD, and can be used to meet US EPA performance-based testing requirements for ULSD.
