摘要
本实验在气相色谱仪上采用热导检测器与氢火焰离子化检测器联用,运用阀切换与填充柱检测汽车尾气中的氮氧化合物、CO、CO2及空气组分,运用毛细柱检测尾气中的碳氢化合物。实现汽车尾气多种组分(HC、CO、NOx等)在同一台仪器上进行检测。
This experiment we used a TCD and FID gas chromatography, to detect nitrogen oxides, CO, CO2 and air in the automobile exhaust by the valve switching and packed column, detecting hydrocarbons in the exhaust by capiliary column. Realization of automobile exhaust component （HC, CO, NOx） was detected in the same instrument.
