Atmospheric aerosols consist of liquid or solid particles suspended in the air. They are formed from a large number of primary and secondary sources and have a variable and complex chemical composition. Investigations into secondary organic aerosol formation in the atmosphere can be addressed by laboratory studies which provide the opportunity to control reaction parameters because experiments can be performed on single compounds under well-defined conditions. The laboratory experiments are performed on selected aromatic compounds to determine aerosol formation yields and a novel denuder-filter sampling system is used to identify gas/particle phase products.
Initial research involves developing a new analytical method for the determination of the gas and particle phase atmospheric oxidation products containing the hydroxyl functionality (acids and phenols) by gas chromatography with mass spectrometry (GC-MS) analysis.
