摘　　要：采用毛细管色谱柱气相色谱法,并采用冷冻样品直接进样技术分析氯乙烷的纯度和杂质,色谱运行时间为14 min,检出了12个杂质组分峰,纯度定量的RSD仅为0.002%。The purity and impurity content of ethyl chloride were analyzed by capillary column gas chromatography with the technique of directly injecting frozen samples. The operation time was 14 min, 12 impurity peaks were detected and the purity RSD was only 0.002 per cent.
