Ensure Accurate Results for Sulfur and Chlorine Analysis in Biodiesels

Typical biodiesels are known to have an oxygen concentration which is higher than that of traditional diesels. This high oxygen content (most commonly between 9 – 11 wt%) can cause XRF analyzers to report lower sulfur and chlorine concentrations due to absorption of the XRF signal by the oxygen. To account for high oxygen content of biodiesel and potential low bias results when measured on a non-oxygenated calibration, the simple use of a correction factor or matrix matching is recommended.
