## Abstract A simple and versatile system is described for the on‐line 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

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
