Abstract Low molecular weight gas phase carbonyls in tobacco smoke are separated as 2,4-dinitrophenylhydrazones and determined by reverse phase high performance liquid chromatography. A trapping procedure is used whereby the gas phase carbonyls are reacted with the derivatizing reagent in a closed system. The deliveries of acetaldehyde and acrolein are compared with published data. In addition, propionaldehyde and acetone deliveries of selected cigarettes are reported.
