Investigation of Liquid Trapping Following Supercritical Fluid Extraction
… lead to analyte loss. This work focussed on the trapping process with the restrictor immersed in a liquid after SFE. Experiments compared the effects of trapping parameters on the collection efficiencies of fat-soluble vitamins of similar polarities and structures. The most important variable was …

Liquid collection efficiencies after supercritical fluid extraction
… after extraction. Currently solid phase trapping and liquid trapping are available for off-line collection of analytes after SFE. A polarity test mix consisting of acetophenone, <i>N,N</i>-dimethylaniline, naphthalene, <i>n</i>-decanoic acid, 2-naphthol, and <i>n</i>-tetracosane was …

The extraction of analytes from aqueous solution using supercritical fluids
… fluid extraction. An off-line solid phase trapping system for SFE was developed. The system trapped the analytes from the SFE effluent onto a solid phase extraction cartridge. The cartridge could then be rinsed in a normal fashion to elute the analytes of interest. Trapping in this way was …
