The formation of organic acids during photooxidation of 1,3,5-trimethylbenzene (TMB) in the presence of NOx was investigated with an online ion chromatography (IC) instrument coupled to a mass spectrometer (MS) at the Paul Scherrer Institute’s smog chamber. Gas and aerosol phase were both sampled. Molecular formulas were attributed to 12 compounds with the help of high-resolution MS data from filter extracts (two compounds in the gas phase only, two in the aerosol phase only and eight in both… CONTINUE READING
