Application of Energy Dispersive X-Ray Fluorescence Spectroscopy to the Analysis of Contaminants in Fuels and Lubricants.
Abstract
A rapid and inexpensive x-ray fluorescence spectroscopic method for the analysis of particulate contaminants has been developed. The method employs the collection of the particulates by filtration followed by x-ray fluorescence analysis of the filter. A unique method for the preparation of standard materials on filters for calibration of the x-ray spectrometer has been developed. Linear response over 2 orders of magnitude is routine. The sensitivity is in the parts per million range. The precision and accuracy is about 3 to 5 percent. The method is currently being used to determine contamination in fuels and to correlate the contamination and wear metal particulates in lubricants with engine wear. A large number of turbine fuels and lubricants have been analyzed and the data obtained have correlated to field performance. (Author)
