title: Rapid PCDD/PCDF screening method for fly ash with ion trap MS/MS.
abstract: A rapid screening method for the polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDF) in fly ash has been developed. The screening is done in two steps: (a) the extraction by the accelerated solvent extraction and (b) the quantitative measurement by ion trap tandem mass spectrometer (MS/MS). Anhydrous sodium sulfate was added to the fly ash containing activated carbon in order to increase the extraction efficiency. The selectivity of the ion trap MS/MS was confirmed with 13C-labelled internal standard. Then the results of the screening method were compared with those obtained by the conventional analytical method using high-resolution mass spectrometer (HRMS).
