One way of collecting extracted analytes after a supercritical fluid extraction (SFE) is to pass the depressurized fluid through a trap composed of a solid adsorbent. The influence of the adsorbent nature on the trap efficiency has been studied. First, the retention factors of each compound of a pol

The rate of extraction of tnacylglycerols with supercntical carbon dioxide can be greatly enhanced by raising the pressure of the fluid to 600 bar, or higher, and its temperature to 60°C, or higher. Both the amount of carbon dioxide and the time required for complete extraction are reduced at such h
