Abstract:

A search was conducted to define all potential spectrometric approaches for conducting wear metal analysis in engine lubricating fluids. The techniques identified were subjected to an analysis of their design and performance characteristics. The resultant data were used to determine which methods had sufficient potential for meeting the needs of the Joint Oil Analysis Program JOAP through the year 2000. The most promising candidate techniques were then ranked through a factorial analysis on the basis of the following criteria analysis time elemental capabilityrange reliabilitymaintainability sizeweight unit cost consumables requirements sample costs safety automation for sampling, calibration, and data reduction simplicity of design simplicity of operation environmental operating limits CRT, printer and data system capabilities particle size capabilities self-diagnosismodular construction reduced operator dependence data management methods and capacity to interface with current JOAP data bases and logistics and maintenance costs. An inductively coupled plasma simultaneous atomic emission spectrometer with auto-dilution and auto-sampling was found to be the best instrumental approach for supporting JOAP needs through the year 2000.
