Abstract : An investigation was conducted in order to evaluate two plasma source emission spectrometers for use in the Air Force Oil Analysis Program (OAP). The high temperatures of the plasma sources were expected to improve the Oil Analysis Program's capability to analyze wear metal particulates. The work is presented in two phases. Phase I of the work dealt with determining the capabilities of the two plasma instruments as well as the currently used OAP spectrometers. During this phase of the work the sample introduction systems were identified as the reason each instrument could not detect particles larger than 3-10 Microns. Phase II of the work dealt with optimizing the sample introduction systems so that particles could be more efficiently transported where they could be analyzed. The improved systems were capable of analyzing particles as large as 14-20 Microns.
