摘要
采用柱切换反吹气相色谱法测定环境空气中的甲烷和非甲烷总烃。通过十通阀切换使甲烷与所有非甲烷烃类化合物彻底分离开来,一次进样可直接测定甲烷和非甲烷总烃。该方法可消除双离子化检测器因灵敏度的差异性引起的误差。方法简单、快速,分析结果准确。
The methane and the non -methane hydrocarbons in air are determined by the column switching back flushing chromatography. The methane and all non- methane hydrocarbons compounds are separated completely through the ten valve switching. Total hydrocarbons and methane are determined directly. The method can elimi- nate the error by double ionization detector for sensitivity differences. The method is simple and fast with accurate results.
