摘　　要：采用顶空进样毛细管气相色谱法测定主流烟气中氰化物的含量,对样品的捕集、制备条件以及顶空条件和气相条件进行了一系列的优化选择。该方法操作简单,线性范围为0.005～50.00μg.mL-1,回收率在90.3%～108.7%之间,对9种卷烟样品进行了测定,结果满意。Headspace （HS） analysis was developed to determine content of cyanide in mainstream cigarette smoke with GC- μECD. A series of conditions were optimized regarding the collection and preparation of samples, headspace conditions, and gas phase status. Results indicated that this method can easily be operated. The linear range was from 0.005 to 50.0μg·mL^-1, and the recovery rate was from 90.3% to 108.7%. Satisfactory results were achieved in the determination of 9 samples of cigarettes with this method.
