Analysis of Additive Elements, Wear Metals, and Contaminants in Used Lubricating Oil According to ASTM D5185: ICPE-9820

Analysis of lubricants added to engine oils such as those used in automobiles and ships is an effective as well as important way to diagnose the state of the engine and other equipment. According to ASTM International Standard D5185 1), inductively coupled plasma (ICP) atomic emission spectrometry with organic solvent dilution is specified for measurement of additive elements, wear metals and contaminants present in used lubricants. Here, using the Shimadzu ICPE-9820 multi-type ICP atomic emission spectrometer, we conducted analysis of 22 elements specified according to ASTM D5185 in samples consisting of a used lubricant (commercially available automotive lubricating oil) and, as a reference, the same, but unused lubricating oil, both of which were diluted with organic solvent.
