| 摘 要： | 建立并验证了采用连续流动分析法(CFA)测定烟草中的氨含量。连续测定的RSD<2%,13个实验室共同实验的重复性和再现性值分别为:r=0.0477x+0.0043(R2=0.930)和R=0.0698x+0.0246(R2=0.980)。不同水平试验的回收率>98%,平均回收率99.7%。分别与HPLC和IC法比较,t检验结果表明CFA与2方法之间均无显著性差异。

| Abstract: | The determination of ammonia in tobacco using continuous flow analysis method was validated.RSD<2%.A collaborative study involving 13 laboratories and 6 samples showed that the repeatability limit(r) and reproducibility limit (R)is linear with ammonia content:r=0.0477x+0.0043 (R2=0.930)and R=0.0698x+0.0246 (R2=0.980).The recoveries of different level>98%, average recovery is 99.3%.Comparing with HPLC and IC respectively, t test shows there are no notable difference between CFA and the two methods. |
