Supercritical fluid chromatography

Microchemical Journal, 1989
Chromatography 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, 1992
The 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)

1994
In 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, 1967
Abstract 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, 1978
AbstractChromatography 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,
