Pulse height analysis of white light scattered from the droplets formed in the CPC condenser was applied to distinguish between homogeneous and heterogeneous nucleation with high butanol supersaturation. With this method the activation of calibration aerosol particles down to ca. 1.5 nm was clearly observable. Experimental results show that the instrument described here is a powerful tool in atmospheric sub-3 nm aerosol particle measurements.
Keywords Condensation particle counter, pulse height analysis, detection efficiency, clusters
