摘　　要：研究了用气相色谱电子捕获检测器(GC-ECD)和气相色谱热导池检测器(GC-TCD)测定发射药老化后N2O含量的方法。考察了电子捕获检测器和热导池检测器对N2O含量的不同测量范围和不同固定相以及不同色谱条件对测定的影响。采用GDX-104为固定相的色谱柱和热导池检测器,对不同批次发射药老化后样品中的N2O含量进行了测定。结果表明,N2O的色谱保留时间在1.6min左右,4批老化后发射药样品中的N2O含量分别为376.8、264.7、1036和1812μL/L,RSD分别为4.11%、2.64%、3.87%和0.78%。Gas chromatographic methods were studied for the determination of N2O in accelerated aging proppelant with electron capture detector （ECD） and thermal conductivity detector （TCD）. The measurement ranges of GC-ECD and GC-TCD, and the influence of different stationary phases and different chromatographic conditions were investigated. The contents of N2O in accelerated aging propellants of different batches were determined by GC-TCD with column of GDX-104 stationary phase. The results demonstrated that the retention time of N2O was 1.6 min, the contents of N2O in accelerated aging propellants of 4 different batches were 376.8, 264. 7, 1036, and 1812 2.64%, 3.87%, and 0.78%, respectively. μL/L, respectively, and the RSDs were 4.11%,
