## 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
## 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,
