Supercritical fluid chromatography

Even though Supercritical Fluid Chromatography (SFC) was first demonstrated by Klesper et al. in 1962, 6 – 7 years earlier than High-Performance Liquid Chromatography (HPLC), its history is unfortunate and it has never been a main stream of chromatography.

Coupling Supercritical Fluid Chromatography to Positive Ion

For industrial processes, capacity is the critical factor. The density of supercritical fluids is intermediate between that of gases and liquids. However the viscosity is lower so we CHEM 4241:Instrumental Analysis Independent Research ProjectSupercritical Fluid Chromatography 2017-10-13 17 hours ago Supercritical fluid chromatography (SFC) is a rapidly developing laboratory technique for the separation and identification of compounds in mixtures. Significant improvements in instrumentation have rekindled interest in SFC in recent years and enhanced its standing in the scientific community.

Melvin is a graduate student in the group of Amos B. Smith III, in the chemistry department at Advances in column technology have led to a renewed interest in supercritical fluid chromatography, which uses a supercritical fluid as its mobile phase. Compared to liquid, supercritical fluids have low viscosities and high diffusivities.

It is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules and can also be used for the separation of chiral compounds. Chromatographic separations with a supercritical fluid as the mobile phase were suggested more than 20 years ago. Availability of commercial hardware makes this technique more widely usable today.
