Abstract：In order to improve the determination efficiency of ammonia (NH3 )in mainstream cigarette smoke,the collection method described in the current standard (YC /T 377—2010)was improved.The Cambridge filter method was established:the mixed solution of ethanol,glycerol,0.20 mol /L HCl (VethanolVglycerolVHCl =415 )was used to prepare the special filter.Cambridge filter trap filled by the special filter was used for collecting ammonia from cigarette mainstream smoke in the process of the conventional cigarette suction.The results showed that:the method achieved excellent reproducibility with inter-assay relative standard deviation of 2.33%,whilst the intra-assay deviation was 1.92%.The recovery was in the range of 93% to 97% and achieved high accuracy;With methods of YC /T 377—2010 the rela-tive standard deviation(RSD)was less than 4.38%.The improrved collection method with simple proce-dure and easy operation,could effectively improve the operating efficiency.
