Abstract. The well-known technique of gas chromatography was used to determine solubilities and liquid-phase diffusion coefficients of trace gases in a thin sulfuric acid film deposited in a fused silica column. Solubilities of SO2, NO2, and N2O4 and the diffusion coefficient of SO2 were measured in the temperature range 203–243 K using sulfuric acid concentrations in the range of 39–83 wt%. The results suggest that sulfuric acid aerosol particles are not a physical sink for these trace gases.
