Monodisperse ammonium bisulfate and pyrene aerosols in the size range of 0.1 to 2 ..mu..m were produced by condensation, and then characterized. A simple generating system developed for routine laboratory operation was found to be well suited for the production of these two different aerosols. The optimum vaporization temperatures and air flow rates were found to be in the range of: 310-390/sup 0/C and 1-3 L/min for ammonium bisulfate, and 150-165/sup 0/C and 1-2 L/min for pyrene. No effect of nuclei material on the particle formation was observed. The ammonium bisulfate aerosol was found to be very sensitive to relative humidity. The aerosols produced from both of the source materials are individual, nearly spherical particles. These monodisperse aerosols are useful for laboratory instrument calibration, inhalation toxicological studies and environmentally related aerosol research. 9 references, 5 figures, 1 table.
