Extraction and analysis of polycyclic aromatic hydrocarbons (PAHs) by solid phase micro-extraction/supercritical fluid chromatography (SPME/SFC)

Abstract
Solid phase micro-extraction (SPME) is a clean and simple pre-concentration method. Previously used for trace analysis of volatil compounds, the use of SPME was extended to non volatil
molecules with the development of an SPME /HPLC interface. This new interface allows the extraction and the analyses of high molecular weight compounds found in aqueous samples. Since
supercritical fluid chromatography is particularly well suited for analysis of complex mixtures containing non volatil compounds, the faisability of coupling SPME and SFC has been investigated
and applied to PAHs.
