摘　　要：以废气中的甲苯作为目标监测物质,研究消除现场废气在线监测中背景组分的干扰问题。结果表明,采用毛细柱MXT-5可实现对甲苯在内的,诸如1,2-二氯乙烷、丙酮、异丙醇、四氢呋喃、甲醇、乙醇等近20种复杂组分气体的分离,在本研究实验条件下可消除对甲苯在线监测的干扰。The study results demonstrate that the use of a MXT-5 capillary column enables the separation of nearly 20 complex component gases,including toluene,1,2-dichloroethane,acetone,isopropanol,tetrahydrofuran,methanol,and ethanol.Under the experimental conditions described in this paper,the interference with toluene online monitoring can be effectively eliminated.
