摘要
使用2.7%DC-200+2.7%QF-1色谱柱氢火焰离子化检测器,以邻苯二甲酸二乙酯为内标物,对间苯二甲腈进行气相色谱定量分析。该方法简便、快速、准确。其标准偏差为0.12,变异系数为0.12%,回收率为99.01%-100.37%。
A method was introduced for the determination of isophthalonitrile by gas chromatography with FID on 2.7%DC-200+2.7%QF-1 column and use diethylphthalate was internal standard. The method is simple rapid and accurate. The standard deviation coefficient of variation and recovery were 0.12 0.12% and 99.01%-100.37% respectively.
