A new analytical technique combining on-line supercritical fluid chromatography with capillary gas chromatography has been developed. The supercritical fluid sample effluent is decompressed througha restrictordirectlyintoaconventionalcapillary gas chromatographic injection port. This technique allow

## 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
## Abstract An on‐line coupled supercritical fluid extraction–liquid chromatography–gas chromatography–mass spectrometry (SFE‐LC‐GC‐MS) system was constructed and applied for the quantitative analysis of selected organic acids. In SFE the analytes were derivatized __in situ__ with pentafluorobenzyl
