离子色谱法测定卷烟主流烟气中氨含量的方法改进
Improvement of Ion Chromatographic Method for Determination of Ammonia in Mainstream Cigarette Smoke
摘要
Abstract
In order to determine the ammonia in mainstream cigarette smoke accurately, ion chromatography (IC) method was improved, and the improved method was applied to determine the ammonia in mainstream smoke of 59 cigarettes measured under ISO and Health Canada (HC) smoking regimes, respectively. The results showed that: 1) The samples were collected, extracted, and purified by graphitized carbon blacks (GCB) column, then determined by ion chromatography using Dioncx IonPac CS16 cation exchange column with methane sulfonic acid (MSA) as eluent. 2) The calibration curve of ammonia was linear in the range of 0 to 1 |ig/mL with the correlation coefficient of 0.9992 and the limit of detection of 0.0067 ug/mL. The recoveries ranged from 96% to 104% with the relative standard deviation of 2.8% to 4.5%. 3) The ammonia measured under HC smoking regime was in the range of 173% to 378% relative to that measured under ISO smoking regime. The problems in sample solution stability and pollution to chromatographic system were eliminated.关键词
