An Atomic Fluorescence System Using a Continuum Source for the Rapid Determination of Wear Metals in Jet Engine Lubricating Oils.
Abstract
A brief review is presented of atomic absorption and atomic fluorescence methods of trace wear-metal analysis of jet engine lubricating oil. The theory of atomic fluorescence in flames is presented for the case of a continuum excitation source. A system for atomic fluorescence measurements is described that employs an electrically-heated graphite rod and a N2O/C2H2 flame atomizer with a 300-W Eimac xenon arc as the continuum excitation source. With this system, small samples (1 microliter) having complex matrices can be analyzed rapidly, conveniently, and with no pretreatment. Analytical calibration curves are given for Cr, Al, and Mo, and these metals are determined in synthetic and real jet engine lubricating oils. The determinations of these elements are evaluated with respect to the accuracy and repeatability criteria of the Interservice Oil Analysis Program. (Author)
