A theoretical and experimental study of the size-dependent counting efficiency of a condensation nucleus counter for aerosol particles in the 2-15 nm diameter range is presented. The condensation nucleus counter (CNC) used in this study is a TSI Model 3020 that was modified specifically for ultrafine aerosol measurement. The instrument is a continuous laminar flow device utilizing convective cooling in the condenser tube to achieve supersaturation of n-butyl alcohol vapor. Details of this instrument have been discussed in previous publications.
