Abstract : Gas-liquid chromatography was used to obtain the volatility profile of various lubricant base stocks and finished crankcase lubricants. The analysis is made possible through the use of a short chromatographic column in conjunction with high operating temperatures. By comparing the chromatograms from commercial lubricants with those from reference materials, it is possible to catagorize the base lubricant according to volatility. Complete analysis is obtained in approximately 15 minutes. Application to used oils is demonstrated by analyzing samples before and after road testing. (Author)
