Analysis of Additive Elements in Lubricating Oil According to ASTM D4951: ICPE-9820

Numerous additives consisting of various types of organometallic substances are added to lubricating oils to enhance performance. It is important to manage the concentrations of these additives for the quality control of lubricating oils. Both ASTM D4951 of the ASTM International standards and JPI-5S-38-2003 of the Japan Petroleum Institute standards (Lubricating Oils - Determination of Additive Elements) specify the use of ICP atomic emission spectrometry with organic solvent dilution as the test measurement method for elements in additives. We performed elemental analysis of the additives in commercially available engine oil, automatic transmission fluid (ATF), and gear oil, using the Shimadzu ICPE-9820 multi-type ICP atomic emission spectrometer, after diluting the samples with an organic solvent.
