摘　　要：采用OV-1和Bentone-34复合固定液研制了大口径二甲苯专用毛细管色谱柱。该柱具有容量大,分离能力强的特点。可同时测定室内空气中的苯,甲苯,二甲苯等有害物质,其二甲苯同分异构体都得到了基线分离。不需富集,室内空气直接进样1 mL分析,最低检测限苯为0.08 mg/m3,甲苯为0.08 mg/m3,二甲苯为0.1 mg/m3。The wide bore capillary column with the superiority in column capacity and separating capability was prepared by use of OV-1 and Bentone-34 composite stationary liquid. The noxious chemicals such as benzene, toluene and xylene can be detected simultaneously, and the xylene isomers can be separated satisfactorily. Indoor air can be injected directly. When the injection is 1 mL, the detection limits of benzene, toluene and xylene are 0.08 mg/m^3 , 0.08 mg/m^3 and 0.1 mg/m^3 , respectively.
