Dioxin contains 75 congeners of polychlorinated dibenzo-p-dioxins (PCDD, and 135 congeners of polychlorinated dibenzofurans (PCDFs). Due to persistency, bioaccumulation, and adverse effect of biotas, PCDD/Fs have attracted widespread concern. Determination of PCDD/Fs in food is challenging due to high demand of sensitivity and selective of the instrument. For a long time, gas chromatography coupled with magnetic mass spectrometry (GC-HRMS) has been used as the gold standard for dioxin analysis. In 2014, GC-MS/MS has also been included as confirmatory method for dioxin analysis by EU committee. In the present study, we applied GCMS-TQ805 NX coupled with boosted efficiency ion source (BEIS) for dioxin analyses. The performance of the instrument was evaluated by low standard solutions and food samples.
