A Combination Flame Atomic Fluorescence—Atomic Emission dc Spectrometer for Analysis of Trace Wear Metals in Jet Engine Oils

Abstract

The combination of flame atomic fluorescence with a continuum source and flame atomic emission was found to provide a convenient method for analyzing Fe, Cu, Ag, and Mg in jet engine lubricating oils in the parts per million range. Dilution of the oils and oil standards to four times the original volume with carbon tetrachloride was found to be optimum for sample preparation.

This burner was developed by Alkemade and his co-workers for fundamental studies in flames. Some of the disadvantages listed above for our Alkemade-type nebulizer–burner were unique to us and are not present in many commercial chamber-type nebulizer burners.
