Abstract
The use of supercritical fluid technology for sample preparation and analysis in the petroleum industry will be described using various examples including: separation of petroleum fuels into hydrocarbon classes, determination of polynuclear aromatic hydrocarbon in soils and petroleum fuels, characterization of fuelβcontaminated soil, assessment of fuel boiling point distribution, determination of polymer additives, and characterization of shale rock and drilling mud.

A procedure is described for the quantitative analysis of (Irganox 1076, Irganox 1010 and Tinuvin 327) in polypropylene matrices using on-line SFE/SFC. The eΓΎ ects of pressure, extraction time, type of matrix (particle or ΓΌlm) and matrix parameters (particle size, ΓΌlm thickness, sample weight) are s
## Abstract Additives and oligomers from polymers were quantitatively extracted and separated using onβline SFE and capillary SFC. Conditions were found which extracted the additives selectively and separated them from the coβextracted oligomers.
