Dioxins analysis in fly ash samples by using GC/MS/MS
Introduction
Dioxins are primarily analyzed by using a gas chromatograph/double-focusing magnetic sector high-resolution mass spectrometer (GC/HRMS) [1, 2]. Recently, however, the EU and China have recognized the use of GC tandem mass spectrometer (GC/MS/MS) for the analysis of dioxins in food and feed [3, 4]. GC/MS/MS is also being considered by the EPA for measurement. Against this background, Japan is exploring the use of GC/MS or GC/MS/MS as alternatives to GC/HRMS. In this application note, we report the measurement result of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in fly ash sample by using a gas chromatograph triple quadrupole mass spectrometer JMS-TQ4000GC (Figure 1). In addition, the obtained measurement results were compared with those of GC/HRMS JMS-800D.
