This document specifies a method for the determination of selected carbonyls (formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, 2-butanone and n<\/i>-butyraldehyde) as their 2,4-dinitrophenylhydrazones in mainstream smoke using reversed phase HPLC-UV\/DAD.<\/p>\n

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.<\/p>\n
