In this paper, an analytical method for the determination of wear meta
ls in engine lubricating oils is described, including wavelengths and
operating conditions. An Inductively Coupled Plasma-Optical Emission S
pectrometer (Perkin-Elmer Optima 3000) is utilized. Results are presen
ted based on the analysis of NIST SRM 1085 Wear Metals in Lubricating
Oil.
