本文件规定了一种使用反相高效液相色谱-串联质谱（LC-MS/MS）对主流香烟烟雾总颗粒物中四种烟草特有亚硝胺（TSNAs）进行定量的方法。定量的TSNA包括:N-亚硝基鸟嘌呤（NNN）、N-亚硝基鸟嘌呤（NAT）、N-亚硝基鸟嘌呤（NAB）和4-（甲基亚硝胺）-1-（3-吡啶基）-1-丁酮（NNK）。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a method for the quantification of four tobacco specific nitrosamines (TSNAs) in the total particulate matter of mainstream cigarette smoke by using reversed phase high performance liquid chromatography with tandem mass spectrometry (LC-MS/MS). The quantified TSNAs are: N-nitrosonornicotine (NNN), N-nitrosoanatabine (NAT), N-nitrosoanabasine (NAB) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK).All current amendments available at time of purchase are included with the purchase of this document.
