| Abstract: | 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%～101.8% and maximum standard deviation of 0.004. |
