The use of energy-dispersive X-ray fluorescence (EDXRF) spectroscopy to reduce production delays from days to minutes in the at-line analysis of sulfur in fuels is discussed in a new application brief from SPECTRO (Mahwah, N.J.). “At-Line Analysis of Sulfur in Fuels According to ASTM D4294 Using ED-XRF Spectroscopy” details tests that compare laboratory and at-line analyses of sulfur in fuels and production samples. The at-line analysis was conducted using a SPECTROSCOUT portable spectrometer, which provided laboratory-level accuracy, required minimal sample preparation, high reliability and showed compliance with criteria set out in ASTM D4294. Also included is guidance for the specification and selection of an at-line EDXRF system, including factors to consider when comparing EDXRF spectrometers.
