Low Sulfur Analysis in Automotive Fuels with Benchtop XRF Analyzer

Testing for sulfur concentration in automotive fuels is common best practice, since the sulfur concentration is indicative of the quality of the fuel. Generally speaking, the lower the sulfur concentration, the higher the quality of the fuel. The ability to determine sulfur concentration in automotive fuels is necessary both for QA/QC purposes and for processing purposes. The amount of sulfur in fuel is also regulated on the state, national, and international level.

X-ray Fluorescence (XRF) is an accepted and recommended technique for analysis of low sulfur (S) in automotive and other fuels. ASTM D7220 – 06 provides guidelines as to the standard test method for sulfur in automotive fuels by polarization XRF.

Benchtop XRF Analyzer—with a detection limit of = 0.5 ppm sulfur—is an outstanding choice for the analysis of low sulfur in automotive fuels in accordance with ASTM D7220-06. Fast, extremely accurate, and with excellent repeatability, a Benchtop XRF Analyzer provides simultaneous analysis of sulfur and other trace elements in automotive fuels.

A detailed applications report describing the degree of accuracy, repeatability, and ease-of-use of Benchtop XRF Analyzer is available.
