摘要
建立丙烯腈杂质分析的毛细管色谱分析方法。用氢火焰离子化检测器,Rtx-624毛细管色谱柱分离,校正归一化法定量计算。结果表明:本方法灵敏度高,分析准确度可靠,且分析时间较短,适合测定工业用丙烯腈纯度和杂质含量。
A method of capillary tube chroma c analysis for the impurities of acrylonitrilewas set up, in which the flame ionization detector and Rtx -624 capillary tube were used, and the normalization with calibration was used as calculation means. Results showed that this method was sensitive, accurate, and efficient. It was fit for the measurement of the acrylonitrile purity and the impurities content.
