At PEFTEC 2019, Bruker will be spotlighting their S2 POLAR which masters all requirements for sulphur analysis, from diesel to crude oils. This also includes continuous process control of higher sulphur levels in refineries as well as norm-compliant Ultra-Low Sulphur (ULS) analysis of final products. The S2 POLAR complies with the international Sulphur norms such as ASTM D7220, D4294, and ISO 13032. With its capability to measure multiple elements simultaneously, including Cl for corrosion prevention and P against residue build-up, 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, which includes the elements Mg, P, S, Cl, Ca, Zn, and Mo.
