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。
