Rapid Sara Seprations by High Performance Liqid Chromatography

Abstract

This paper presents both rapid analytical and preparative high performance liquid chromatographic (HPLC) techniques for separating liquid-fuel type materials into saturates, aromatics, resins, and asphaltenes (SARA). The preparative method, an adaptation of a technique developed by Jewell, et. al. (1, 4), significantly decreases analysis time. The analytical technique utilizes HPLC to achieve the same separations in less time.
