摘　　要：以异丙醇为溶剂,茴香脑为内标,采用HP-1MS毛细管柱(30m×0.25mmi.d×0.25μmd.f),建立了卷烟烟气总粒相物中三醋酸甘油酯的气相色谱/质谱分析方法。该方法的线性范围为0.0323～0.776mg·mL-1(r=0.99997),平均回收率为99.13%,RSD为0.83%。并应用该法测定了部分卷烟烟气总粒相物中三醋酸甘油酯的含量。A method for determining triacetin in cigarette smoke condensates by GC/MS with an HP-1MS capillary column (30m×0.25mm i.d×0.25μm d.f) and anethole as an intenal standard. The linear range of this method was from 0.0323 to 0.776mg·mL^(-1) triacetin (r=0.99997).The average recovery of triacetin was 99.13% and the RSD of this method was 0.83%. The contents of triacetin in some cigarette smoke condensates were determined with this method.
