Fundamental Investigations of Supercritical Fluid - DiVA

Kromatografi med koldioxid som mobil fas - Life Science

Instrumentation employed for supercritical fluid chromatography is depicted. A wide variety of SFC applications are introduced. In this context, supercritical fluid chromatography (SFC) represents a promising alternative approach to improve the metabolome coverage, while further increasing the analysis throughput. SFC, which uses supercritical CO 2 as mobile phase, leads to numerous advantages such as improved kinetic performance and lower environmental impact. 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.

We already know that SFC is fast. But thanks to the lower viscosity of CO2 versus your typical reverse phase, normal phase, or HILIC solvents, one can ramp up the flow rate and achieve satisfactory chromatography in a fraction of the time. Chromatography, Supercritical Fluid Kromatografi, överkritisk Engelsk definition. A CHROMATOGRAPHY method using supercritical fluid, usually carbon dioxide under very high pressure (around 73 atmospheres or 1070 psi at room temperature) as the mobile phase. 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.

For laboratories overwhelmed with solvent disposal and time-consuming solvent cleanup, supercritical fluid chromatography (SFC) is a beneficial alternative to purification and analytical applications. Thefirst reportofthe useofsupercritical fluids as mobilephases in chromatography was published in 1962 by Klesper andco- workers (3), who used supercritical Freons as the carriers for Supercritical fluid chromatography Supercritical fluid chromatography (SFC) can be used on an analytical scale, where it combines many of the advantages of high performance liquid chromatography (HPLC) and gas chromatography (GC).

Pat Sandra . e-seminar November 16, 2011 Supercritical fluid chromatography (SFC) is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase.
