Preparative Supercritical Fluid Chromatography
Supercritical Suid chromatography (SFC) on a preparative scale is of interest because of its advantages over high performance liquid chromatography (HPLC). The high diffusivity and low viscosity of supercritical Suids allow rapid separation. The solvent strength can easily be controlled by changing pressure and/or temperature, so that mobile phases with a Rxed composition can be used to separat...

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...
متن کاملLipidomics by Supercritical Fluid Chromatography
This review enlightens the role of supercritical fluid chromatography (SFC) in the field of lipid analysis. SFC has been popular in the late 1980s and 1990s before almost disappearing due to the commercial success of liquid chromatography (LC). It is only 20 years later that a regain of interest appeared when new commercial instruments were introduced. As SFC is fully compatible with the inject...
