This Recommended Method is applicable to the determination of selected carbonyls (formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, 2-butanone and n-butyraldehyde) as their 2,4-dinitrophenylhydrazones in mainstream smoke from cigarettes with ISO NFDPM yields between 1 mg/cigarette and 15 mg/cigarette using reversed phase HPLC-UV/DAD.

The described method is specified using ISO 3308 and ISO 20778 (Intense) smoking parameters. The use of these machine smoking parameters reflects their inclusion in the reporting requirements of various national regulations rather than an endorsement of their appropriateness by CORESTA.
