Set It and Forget it Long-term Stability of Sulphur Analysis by XRF

Precision over time is a must-have in petrochemical analysis, and PANalytical?s high-throughput wavelength dispersive X-ray fluorescence (XRF) spectrometry solution can deliver the certainty that the oil industry needs. Industry methods, such as ISO 20884:04 and ASTM D2622-08, are utilized to monitor sulphur in road fuels within strict limits. Importantly, these methods also scet the standard for analytical repeatability and reproducibility. In this article, we take a look at the performance of PANalytical?s Axios-Petro high-throughput XRF spectrometer for sulphur analysis ? at the ?20 consecutive measurement? specification set out in ISO and ASTM norms. New data, assessing precision out to 122 days is also presented.
