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.

Safe Liquid Sample Handling with SampleCare™

Highest instrument uptime is crucial for the operation. This is ensured with Bruker’s SampleCare technology. SampleCareTM prevents leakages of liquid samples and protects important system components. This guarantees maximum instrument availability.

For the mentioned petrochemical standards are pre-installed Ready-to analyze solutions available. These S2 POLAR ‘One Button’ solutions minimize instrument set-up time and lead to an economic and cost-effective element analysis and pay back immediately.
