Organic aerosols in the atmosphere are one of the largest uncertainties in trying to predict climate change. Their formation processes are poorly understood and recent evidence has shown that even volatile compounds not expected to have a role in particle formation may be a significant source of secondary organic aerosols. One of the difficulties in trying to study SOA is the huge number of compounds present. This talk will highlight some of our recent advances in understanding aerosol formation, properties and sources using state of the art chromatographic techniques. We have simulated organic aerosol in smog chambers and compared this to urban, marine and tropical environments using high resolution two dimensional gas chromatography (GCXGC) and liquid chromatography coupled to mass spectrometry (LC-MS).
