2.4-二硝基甲苯的气相色谱分析

Analysis of 2.4-DNT by Gas Phase Chromatography

建立了以丙酮溶解试样，经OV-225石英毛细管柱分离的2．4-二硝基甲苯气相色谱分析方法。平均回收率为98．92％～104．69％，标准偏差（δ）为0．0020--0．0097，相对标准偏差（RSD）为0．0098％-2．58％，为工业品2．4-二硝基甲苯的质量控制提供了一个简便、准确、快速的分析方法。

The sample was dissolved with acetone and separated with OV-225 quartz capillary, a gas phase chromatography method for the determination of 2,4-DNT was established. The average coefficient of recovery was 98.92%--104.69%, the standard deviation （δ） was 0.0020--0.0097,the standard deviation （RSD） was 0.0098% --2.58%.
