Abstract
The sampling and analysis of carbonyls formed during the photooxidatio n of selected monoterpenes (alpha-pinene, beta-pinene, limonene) in ai r is investigated. A method using 2,4-dinitrophenylhydrazine coated C- 18 cartridges which allows the specific analysis of aldehydes and keto nes as their hydrazones down to sub ppb-level is applied. A wide range of products was analysed including 6,6-dimethylbicyclo[3.1.1]heptan-2 -one, 3-(1-methylethenyl)-6-oxo-heptanal and pinonaldehyde which are t he main atmospheric oxidation products of beta-pinene, limonene and al pha-pinene, respectively.
