摘要
为了提高卷烟主流烟气中氨的测定效率,对现行标准YC/T 377—2010中氨的捕集方法进行改进,提出剑桥滤片收集卷烟主流烟气中氨的方法：将乙醇、甘油、0.20 mol/L浓度的盐酸溶液按照4∶1∶5体积比配制滤片处理溶液,用装有经滤片处理液处理后的剑桥滤片的捕集器,在常规的卷烟抽吸中,实现卷烟主流烟气中氨的捕集.结果表明：剑桥滤片法的日内重复性的相对标准偏差〈2.33%,日间重复性的相对标准偏差〈1.92%,数据精密度良好;加标回收率93%~97%,方法准确性较高;与YC/T 377—2010方法比对结果的相对标准偏差〈4.38%,二者结果一致.改进后的捕集方法程序简单、易于操作,可有效提高操作效率.
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（ Vethanol∶Vglycerol∶VHCl= 4∶1∶5） 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 relative standard deviation（ RSD） was less than 4. 38%. The improrved collection method with simple procedure and easy operation,could effectively improve the operating efficiency.
