Energy-Dispersive X-ray Fluorescence (EDXRF) for the Petrochemical Industry A true Multi-element Analyzer, for Sulfur and more The S2 POLAR is a true multi-element analyzer and combines the performance of several single-element analyzers in a one-does-it-all powerful benchtop instrument. The S2 POLAR masters all requirements for S analysis from diesel to crude oils. This also includes continuous process control of higher sulfur levels in refineries as well as norm-compliant Ultra-Low Sulfur (ULS) analysis of final products. The S2 POLAR complies with the international S norms such as ASTM D7220, D4294, and ISO 13032. With its capability to measure multiple elements simultaneously, including important elements in process control such as Ni, V, Fe and CI, the S2 POLAR is well suited for the analytical demands of refineries in one single instrument. The S2 POLAR is also well suited for the norm-compliant analysis of additives in lubricating oils according to ASTM D6481 and ASTM D7751 that includes the elements Mg, P, S, Cl, Ca, Zn, and Mo. Furthermore this also includes the analysis of elements in edible oils or palm oils.
