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.
