Analytical methods for determining composition of new and used synthetic k~bricants have been developed as an important part of the Army's lubrication research effort. A logical approach for the systematic analysis of lubricants has been applied to a wide variety of selected military and commercial lubricants. Hybrid lubricant blends of synthetic hydrocarbons, esters, and mineral oils have been separated and analyzed through the combined use of spectroscopy and chromatopapt~y. Ester fractions have been fi~rther evaluuted by chen~ical hydrolysis and derivatization to determine exact composition of the parent acidic and alcoholic components. While characterization of lubricants to include more detailed additive compositionis not yet complete, expanded analytical approaches to provide compositional information for improved base stock definition have been enhanced.
