## 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
Meat products that were exposed to a warehouse fire were collected and examined to identify contaminants present in the samples. An extraction method using supercritical carbon dioxide at 100 atm and 60°C was developed to analyse and characterise volatile and semi-volatile compounds from the samples
