## Abstract A polarity test mix consisting of acetophenone, __N__,__N__βdimethylaniline, naphthalene, 2βnaphthol, and __n__βtetracosane was spiked onto sand and extracted with carbon dioxide modified with acetonitrile, methanol, or toluene. The extracts were collected in chloroform, hexane, methano

## Abstract Capillary supercritical fluid chromatography has been directly coupled with supercritical fluid extraction using modified carbon dioxide. The mixed fluids were prepared with a single pump onβline mixing system. The most important step in the SFEβSFC interface was the elimination of the
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
