The effect of concentratingsemi-v olatile aerosols usinga water-condensation echnology was investigated using
the Versatile Aerosol Concentration Enrichment System (VACES) and the Aerodyne Aerosol Mass Spectrometer
(AMS) duringmeasurements of ambient aerosol in Pittsburgh, PA. It was found that the shape of the sulfate
mass-weighed size distribution was approximately preserved during passage through the concentrator for all the
experiments performed, with a mass enhancement factor of about 10–20 dependingon the experiment. The size
distributions of organics, ammonium and nitrate were preserved on a relatively clean day (sulfate concentration |
