摘　　要：介绍了用双柱双氢火焰离子化检测器同时进样气相色谱法分析气体样品中非甲烷烃。经过与现有方法的比较,该方法具有平行性更好、数据更准确、分析速度快等优点,各项指标均大大优于现行标准HJ/T 38-1999中的数据。通过软硬件的改进,解决了以前非甲烷烃在分析中由于在时间上所引起的数据倒置、分析误差等问题。Non-methane hydrocarbons in the gas sample are analyzed simultaneously by GC with double columns and double FIDs. Compared with existing methods, this method had the advantages of good parallelism, good veracity, good analytical speed, and etc. All of the parameters were superior to the data of current standard HJ/T 38 - 1999 greatly. Through improving the hardware and the software, this method resolved the data inversion and the analytical error caused by time also.
