SFC is essentially a normal-phase chromatographic technique with inherent high speed and efficiency due to its mobile phase. Technique in which the mobile phase fluid is maintained at temperatures somewhat above its critical point.

On-Demand Webinar Available Now! Initial download of the metrics may take a while. The interest of supercritical-fluid chromatography SFC is that high temperatures are not needed to elute heavy ends and that the mechanism for extending the upper limit of simdist depends supervritique on sample solubility into the supercritical mobile phase. Once the optimal mobile phase and stationary skpercritique are determined from screening, the method can be easily scaled for purification on the same system.

Simulated distillation simdist based on separation using gas chromatography GC is widely spread in the petroleum industry for evaluation of fossil fuels as well as petroleum feeds and cuts produced by refining and conversion processes. Current usage metrics About article metrics Return to article. Thus, SFC could be the tool of choice for better determination of conversion in heavy petroleum-fraction processing.

SFC excels at separating and purifying chiral compounds and natural products chromatograhie it’s faster, uses much less solvent, and overall is a less expensive and greener method that exceeds high pressure liquid chromatography HPLC in performance for chiral separations.

The mobile phases used in SFC are gases such as freon, ethylene, or carbon dioxide.
