Vapour pressures of organic components and hygroscopicity of binary organic/water and ternary organic/inorganic/water aerosol using optical tweezers.

David J. Stewart, Chen Cai and Jonathan P. Reid

Quantifying the gas/particle partitioning of organic compounds is of great importance for understanding the atmospheric chemistry of aerosol particles and gas phase semi-volatile organic compounds. Recently, we have developed a new method for the retrieval of vapour pressures of SVOCs from single aerosol droplets in an aerosol optical tweezers system.
