Lubricating oils are generally formulated with additives which have varying modes of action including as detergents, anti-oxidants and anti-wear agents. These additives can contain calcium, copper, magnesium, phosphorus, sulphur and zinc. Chlorine can also be present in these oils as a contaminant. The ASTM Standard Test Method D6443 can be used to determine if the oils, additives and additive packages meet specifications with respect to the added elements and with respect to chlorine contamination.

The analysis of lubricating oils by WDXRF provides a non-destructive method that is easily incorporated into a production environment. This report covers the performance of the S8 TIGER for ASTM D6443 including precision and Lower Limits of Detection (LLD).
