## Abstract An onβline supercritical fluid extraction/capillary supercritical fluid chromatography system was developed using a capillary trap with stationary phase and a linear restrictor. With the system, samples can be injected into either the supercritical fluid chromatography (SFC) column or t

## Abstract Analysis of low concentration polymer additives has been a challenging problem. The commonly used methods of analysis involve the initial extraction of polymer additives with solvents, often in a Soxhlet apparatus, followed by liquid, size exclusion, or gas chromatography. This paper de
Soxhlet and sonication techniques have been widely used for extracting semivolatile organic compounds from solid matrices regardless of the fact that these methods are time consuming and costly in amount of solvent required. In recent years, supercritical fluids have gained increased interest as ext
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
## Abstract For many applications using supercritical fluid extraction (SFE), modifiers may be required.This paper will present some findings regarding the use of various modifiers including methanol, hexane, acetone, chloroform, dichloromethane, toluene, and tributylphosphate, in onβline and offβl
