Abstract

Determination of Carbonyl Compounds and Organic Acids in the Atmospheric Gas-phase and their Influence on Oxidation Capacity Guest contribution M. Kibler, S. Schlomski and K. Bachmann Darmstadt University of Technology, Petersenstr. 18, D-64287 Darmstadt, Germany Introduction Carbonyl compounds and carboxylic acids are the first stable intermediates in the oxidation of hydrocarbons. Their concentration and appearance depend mainly on the photochemical breakdown caused by radicals and photo-oxidants like OH, NOs and ozone. These measured components should give information about the origin and extent of primary emissions (biogenic/anthropogenic) and the photochemical age of the analysed air. To get information about primary and secondary sources the identification of as many components as possible in field experiments is required.
