Chromatography with Supercritical Fluids
Science, 1987In 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, 1988Glucose 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).

Supercritical fluid chromatography
Microchemical Journal, 1989Chromatography with a supercritical fluid as mobile phase was first reported more than twenty years ago [1], although only in recent years have its advantages been realized. These are especially relevant to oligomers, polymers, and polymer additives, and supercritical fluid chromatography (SFC) is finding increasing use in analyses in polymer chemistry.

Supercritical fluid chromatography
Russian Chemical Reviews, 1992The characteristic features of supercritical fluid chromatography (SCFC) are examined and there is a brief historical note concerning the development of the method. Information concerning the use of supercritical fluid chromatography in the analysis of objects of different nature is presented in the form of a table.

Chromatography with Supercritical Fluids (Supercritical Fluid Chromatography, SFC)
1994In a chromatographic separation a mixture of substances is transported by a carrier, called mobile phase, along a not moving surface, called stationary phase. Chromatography is therefore a separation based on two mass separating agents: the mobile phase and the stationary phase. Between the two phases mass transfer processes take place, which lead to a

Chromatography with supercritical fluids
Analytica Chimica Acta, 1967Abstract Molecular interactions in the gas phase may be utilized for enhancing the volatility of substances in gas chromatography. A study of the effect of pressure on equilibria in GLC revealed that at higher pressures these interactions are quite appreciable, especially near the critical point.

Chromatography with Supercritical Fluids
Angewandte Chemie International Edition in English, 1978AbstractChromatography with supercritical fluids unites the features of both gas chromatography and liquid chromatography, yet retains special characteristics of its own. The diffusion coefficient and particularly the viscosity of fluid phases may approach values for low‐pressure gases, while the solvent power may be similar to that of liquids. However,
