摘要
Abstract
In order to rapidly determine ammonia in mainstream cigarette smoke, an improved method of ion chromatography was developed by trapping ammonia in gas and particulate phase using a Cambridge filter pad pretreated with ethanol-water solution of hydrochloric acid under both the ISO and Canadian intense smoking regimes. Results showed that this method eliminated the process of installation and removal of impingers so that experiment efficiency was improved. Limit of detection for ammonia was 0.021μg/mL. The method achieved excellent reproducibility with inter-assay RSD of 4.25% and 4.68%, whilst intra-assay RSD was 3.97% and 4.37% under ISO and Canadian intense smoking regime. The recovery was in the range of 95.06% - 97.18%. The test data of the same samples using the method showed no significant difference compared with those using standard method of tobacco industry YC/T 377-2010.关键词
