Abstract

The on-line combination of supercritical fluid extraction (SFE) with gas chromatography (GC) and mass spectrometry (MS) is a promising technique for the analysis of semi-volatile organic compounds (SVOC) and particulate organic matter (POM) in in-house dust and indoor air. This paper reports on the test and modification of a commercial on-line SFE-GC combination with a cryotrap outside the GC oven. Modifications, in particular of the cryotrap, are described, after which n-alkanes from C(9) to C(40) could be transferred quantitatively from the extraction cell to the GC column. With the modified instrument SVOC and POM in-house dust and indoor air samples have been analysed. Preliminary results are reported which show strong similarities between lipophilic extracts of different house dusts and of a house dust and a 1 m3 indoor air sample collected on a polyurethane foam plug.
