Abstract

The effect of fluid density on solute retention using a mobile phase containing 3% (v/v) propan-2-vol in pentane has been investigated. A linear relationship was established between solute retention times and mobile (fluid) phase density. A new method for the determination of the critical temperature of mobile phase mixtures is described and the chromatographic integrity of gas, supercritical fluid and high-performance liquid chromatography is demonstrated.
