✦ Synopsis

Addition of 2-propanol, acetonitrile, or dichloromethane to a supercritical carbon dioxide mobile phase in capillary supercritical fluid chromatography decreased the retention of selected test solutes at constant temperature and pressure. The data obtained indicate that selective interactions between the solute and the mobile phase modifier contribute to the retention mechanism. High-molecular-weight polycyclic aromatic compounds were chromatographed with 8.9 mol% 2-propanol in carbon dioxide.

A small percentage (0.3 % w/w) of formic acid was added to supercritical carbon dioxide to increase mobile phase polarity and improve separation of polar solutes on three different commercially available capillary columns.

## Abstract Capillary supercritical fluid chromatography has been directly coupled with supercritical fluid extraction using modified carbon dioxide. The mixed fluids were prepared with a single pump on‐line mixing system. The most important step in the SFE‐SFC interface was the elimination of the
