Title

Solvating Gas Chromatography

Abstract

Solvating gas chromatography (SGC) is a variation of supercritical fluid chromatography that offers high speed separations for certain compounds. The mobile phase in SGC enters the column as a supercritical fluid and leaves the column at atmospheric pressure. As the pressure of the mobile phase drops, it loses solvating power. This loss of solvating power results in a spatial focusing of the analyte, but it also increases the time less volatile analytes spend on column. We are applying a thermal gradient along the column to decrease the elution time.  Laser-induced fluorescence is used as a detection method to monitor elution times, resolution, and band focusing of the analyte.
