Abstract

For number concentration measurements of superfine particles a condensation nucleus counter (CNC) is frequently used. The combination of a new CNC module with a white light aerosol spectrometer and a passive collector makes possible accurate time-resolved determination of particle number within the overall size range of 10 nm to 40 μm and at concentrations up to 105 particles/cm³. With the aerosol spectrometer a high time-resolved particle size determination is also possible in the size range of 0.3–40 μm up to the same high number concentrations of 105 particles/cm³.
