• Abstract: A method for the determination of Trace Ethylene dichloride (EDC) by prima δB process industrial mass spectrometer was established. The method can be used for on-line quantitative analysis of trace EDC in the inlet gas on the experimental device of ethylene epoxidation reaction. Compared with off-line chromatographic analysis, mass spectrometry analysis is fast and convenient for real-time tracking of EDC at the inlet of the experimental device, and the error caused by the analysis results in the sampling process of off-line chromatographic analysis is eliminated. 建立了Prima δB 过程工业质谱仪测定微量二氯乙烷（EDC）的分析方 法，在乙烯环氧化反应实验装置上，使用该方法能够对入口气体微量EDC 进行 在线定量分析。与离线色谱分析相比，质谱法分析速度快，便于对实验装置入 口气体EDC 进行实时跟踪，同时排除了在离线色谱分析取样过程中对分析结果 造成的误差。
