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

## 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 Nerve agents and two other chemical warfare agents were extracted from spiked soil with supercritical CO~2~. Supercritical fluid extraction (SFE) was used as an offβline technique. The extracts were analyzed with a twoβchannel capillary gas chromatograph, equipped with an autosampler an
