Precision comparison between ASTM test methods D7039, D2622, and D5453

As regulators across the globe move to more restrictive regulations on sulfur content in a variety of fuels, there is a furthered need to maximise the precision of analysis methodologies. With multiple methodology options for sulfur analysis available, care must be taken to select a method that produces the least amount of variability in measurements.

ASTM Proficiency Testing Programs are statistical quality assurance programs that enable laboratories to evaluate and improve performance. This paper will discuss the ASTM PTP for sulfur results for reformulated gasoline and ultra low sulfur diesel programs from 2019 - 2021 using the most common test methods for low sulfur automotive fuels: D7039, D2622, and D5453.

Learn which method demonstrated the best performance for reproducibility, and how XOS' D7039 analysers demonstrate excellent precision in both D7039 and D2622 mode.
