## Abstract A key feature differentiating analytical supercritical fluid extraction (SFE) from conventional liquid extraction is the possibility of varying the solvent strength of a supercritical fluid to achieve selective extractions of specific target compounds, or functional classes of compound,

## Abstract A simple and versatile system is described for the onβline coupling of SFE to capillary GC. The interfacing consists of a programmed temperature vaporizer (PTV) injector. With this injector it is possible to combine solute trapping, elimination of a high flow of extraction fluid, and qu
## Abstract Polymer additives were extracted from polyethylene with supercritical carbon dioxide. The twoβfilm theory, which considers mass transfer across a phase boundary, is applied to qualitatively describe the kinetics of mass transfer from the core of the polymer particles into the supercriti
A quantitative comparison between off-line supercritical fluid extraction (SFE) and a classical solvent extraction of a limonoid compound is discussed. A two-level, three factor factorial analysis was used to optimize the variables, pressure, temperature, and the length of extraction time. By a stat
