Sulfur concentrations are strongly regulated in automotive fuels. The current sulfur limit is at 10 ppm in many countries and others are to follow. This specification leads to an increasing demand in monitoring such ultra-low sulfur (ULS) limits for diesel and gasoline, not only in refineries but also along the supply chain including transport in pipelines and storage at terminal stations. Finally these limits are supervised by external service laboratories and inspection laboratories, either for comparative measurements or for customs and tax purposes.
X-ray fluorescence (XRF) is the perfect method for all these applications. Easy-to-use with straightforward sample preparation: The S2 POLAR masters all requirements for S analysis from diesel to crude oil. This includes continuous process control of higher sulfur levels in refineries and norm-compliant ultra-low sulfur analysis of final products.
