摘　　要：针对进口混合芳烃中的“X”类有毒物质，建立混合芳烃中三甲苯含量的气质联用（GC—MS）测定方法。运用气相色谱质谱的微分流技术，对混合芳烃中的3种三甲苯的同分异构体进行定性和定量分析，该方法准确度高，回收率99．06％101．8％，最大标准偏差0．04％。In order to determine the ＂X＂ series and poisonous materials, a method was proposed for the determination of trimethylbenzene in import mixed aromatics. The paper determined three isomer of trimethylbenzene in mixed aromatics on quantity and quality by using MICROFLUIDIC SPLITTER and GC-MS/FID. The method was high accuracy with the recovery of 99.06%-l 01.8% and maximum standard deviation of 0.004.
