P, S, Ca and Zn in lube oil per ASTM D6481

AppNote XRF1312: analysis of P, S, Ca and Zn in lube oil per ASTM D6481

Background

Measurement of P, S, Ca and Zn in lube oil is demonstrated as per ASTM D6481. ASTM D6481 is a standard test method for measuring lube oil using EDXRF. The elements and concentration ranges covered by D6481 are specified in Table 1 of the method. Quality control and quality assurance during the lube oil manufacturing process is essential, as various formulations for give different lubricity properties. A fast, simple method of analyzing lube oils is important throughout the QC/QA process. Rigaku meets this industry need with a high performance low cost benchtop EDXRF system. Rugged and reliable, the NEX QC+ is an ideal tool, with simple and intuitive software for the non-technical operator.
