Chromatography with Supercritical Fluids

Science, 1987
In supercritical fluid chromatography (SFC) the mobile phase is neither a gas nor a liquid, but is a supercritical fluid. As a result of the unique properties of supercritical fluids, SFC is rapidly becoming a prominent separation technique for the analysis of reactive, thermally labile, and nonvolatile compounds.

Supercritical fluid chromatography of glycosphingolipids

Analytical Biochemistry, 1988
Glucose polymers and three classes of glycosphingolipids were permethylated and studied by supercritical fluid chromatography using a DB-5 coated capillary columns and carbon dioxide as the mobile phase. Column restrictors were fabricated at each column tip as described by E.J. Guthrie and H.E. Schwartz (1986, J. Chromatogr. Sci. 24, 236).
