Popis:	In trace analysis of the polychlorinated dibenzodioxins (PCDD) and -furans (PCDF) simple adsorption Chromatographic procedures for matrix removal are shown to be highly successful. In the case of a complex matrix a combination or even a repetition of different separation steps is necessary. The independent, flexible combination of separation steps (modular approach) makes it possible to find the optimum conditions for the removal of extremely divergent matrices in an easy way. A combination of classical separation steps in organic trace analysis has been successfully applied to the investigation of used motor oil and urban particulates: hexane/DMF partition, adsorption chromatography on various adsorbents (silica, alumina, Mg-silicate) as well as the extractive digestion procedure with concentrated sulfuric acid. In this way it became possible to inject the mass equivalent of 3 g of oil in HRGC/ MSD-analysis.
