Abstract: A method for the analysis of carboxylic acids in aerosols was developed,based on the collection of particles on Teflon filters,extraction with dichloromethane, and derivatation with BF3-methanol followed by analysis of the formed methylesters by large volume injection GM/MS.In aerosol samples from smog chamber experiments with alpha pinene and ozone this method was applied and resulted in the identification for the first time of cis-pinic acid.Being a dicarboxylic acid this product is estimated to posess an extremely low vapour pressure and may thus be an important element in gas-to-particle conversion of alpha pinene.
