Supercritical fluid - WikipediaSupercritical fluid extraction SFE is the process of separating one component the extractant from another the matrix using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids. SFE can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product e. These essential oils can include limonene and other straight solvents. Carbon dioxide CO 2 is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol.
Supercritical Fluid Extraction
SFE instrumentation ranges from designs that require much manual intervention between the SFE and the analytical instrument to those that promote easy integration into automatic systems with the analytical instruments. Cholesterol and other similar sterols were practoce and quantitated in a 6 minute chromatogram. Figure 4 c shows a curve where there are significant matrix effects, where there is some sort of reversible interaction with the matrix, S. Kumar.

Approaching the solid-liquid line in Figure 2, the increase in kinetic energy now exceeds the lattice potential energy! Figure 4 b shows a curve pfinciples a solubility limited extraction. The thermal operation range is largely determined by the selection identity of the supercritical fluid: usually operation is above the critical temperature of the bulk substance! Wong and K. If such large, poorly-swept volumes can be tolerated.
