We provide calibration and monitor samples for the analysis of S in petroleum matrices by XRF. These standards are available in isooctane, diesel and mineral oil for analysis according to ASTM methods D2622, D4294.
The standards are available as individual standards or in complete calibration sets with S concentrations from 0 up to 5% for diesel and mineral oil and up to 3,000 ppm for isooctane. Drift correction samples are also available in polysulfide oil at various concentrations to accommodate your calibration range.
