  • Among the most popular means of mainstream smoke collection for specific analysis are solvent traps. Determination of the carbonyl compounds as their 2,4-dinitrophenylhydrazones(DNPHs) by HPLC offers increased sensitivity and reproducibility in the analysis of mainstream cigarette smoke. In this work, the mainstream smoke of a reference cigarette(lR4F) was collected in four kinds of gas washing bottles and their effects on the analysis of carbonyl compounds were investigated. The results show that the porosity of fritted glass filter in gas washing bottles exerted profound effect on the composition of the carbonyl compounds in mainstream smoke.
