| Abstract | This report details work performed on the study of aerosol formation in a photochemical fast flow reactor which may be operated in a 'wall free' mode. Aerosols have been produced in this reactor in irradiated dry air containing typically 0.8 ppm NO2 and 10 ppm of one hydrocarbon. The hydrocarbons studied were alpha-pinene, 1-hexene, cyclohexene, 1-dodecene, toluene, m-xylene, 1,3-hexadiene, and 1,5 hexadiene. The effect of the addition of various mixtures of SO2, H2O and NH3 to the reactions was studied. Ozone and condensation nuclei concentration were measured in the reactor as a function of reactant concentration. Total mass production was measured by filter collection, and infrared spectra of some of the samples have been obtained. |
