Standard Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-ray Fluorescence Spectrometry – WD-XRF.
RIGAKU offers a selection of WD-XRF solutions which comply with ASTM D2622. A full application note is available on request demonstration the performance of the Micro Z-ULS, the Supermini 200 and the ZSX Primus range.
These application note demonstrates quantitative analysis of sulfur in petroleum products according to ASTM D2622-16 on Rigaku ZSX Primus, a wavelength dispersive X-ray fluorescence (WDXRF) spectrometer.
The equipment specified for Test Method D2622 is restricted to WD-XRF and does not include ED-XRF and therefore this test method is only applied in specific applications. The alternative test method, such as Test Method D4294 offers more flexibility from an instrument choice point of view.
ASTM D2622 is a standard test method for the measurement of Sulfur in petroleum products. This method is particularly used for measuring low levels of S in Ultra Low Sulfur Diesel or ULSD where the concentrations have to be below 10ppm. However this test method can be applied for Sulfur concentrations down to 3 ppm or mg/kg and up to 4.6%.
This test method is designed to cover the measurement of total sulfur in petroleum and petroleum products that are single-phase and either liquid at ambient conditions, liquefiable with moderate heat, or soluble in hydrocarbon solvents.
The range of applications include diesel fuel, jet fuel, kerosene, other distillate oil, biodiesel, residual oil, lubricating base oil, hydraulic oil, crude oil, unleaded gasoline, gasoline-ethanol blends, and naphtha.
There are a number of XRF based methods for measuring Sulfur in petroleum products. These include:
WD-XRF and ED-XRF are not the only approved methods for testing Sulfur in petroleum products. The most common alternative method is based on Ultraviolet Fluorescenceor UVF and is a combustion method.
