Determination of Dioxin in Food by GC-MS/MS Coupled with Boosted Efficiency Ion Source (BEIS)

A boosted efficiency ion source (BEIS) with optimized method was applied for determination the trace level of PCDD/Fs in food by GCMS-TQ8050 NX. The TEQs from GCMS-TQ8050 NX are in good agreement with those consensus values. Dioxin contains 75 congeners of polychlorinated dibenzo-p-dioxins (PCDD, and 135 congeners of polychlorinated dibenzofurans (PCDFs). Due to persistency, bioaccumulation, and adverse effect to 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-TQ8050 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.
