本文件规定了使用反相HPLC-UV/DAD测定主流烟气中选定羰基（甲醛、乙醛、丙酮、丙烯醛、丙醛、巴豆醛、2-丁酮和正丁醛）作为其2,4-二硝基苯腙的方法。 该方法适用于使用反相HPLC-UV/DAD的无尼古丁干颗粒物质(NFDPM)产率在1mg/支和15mg/支之间的卷烟。

This document specifies a method for the determination of selected carbonyls (formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, 2-butanone and n-butyraldehyde) as their 2,4-dinitrophenylhydrazones in mainstream smoke using reversed phase HPLC-UV/DAD. This method is applicable to cigarettes with nicotine-free dry particulate matter (NFDPM) yields between 1 mg/cigarette and 15 mg/cigarette using reversed phase HPLC-UV/DAD.
