Abstract

Two butanol-based Condensation Particle Counters (CPC 3022, CPC 3025), three water-based CPCs (CPC3781, CPC3785${\times}$2), a Gardner Counter, a Fast Mobility Particle Sizer (FMPS), and an Aerosol Electrometer (AE) were deployed to measure the number concentrations from atomized aerosol under six different conditions. Comparisons of particle number concentrations measured by the CPCs, FMPS, and AE were conducted to evaluate the performance of the each CPCs using laboratory generated artificial particles such as NaCl, succinic acid ($C_4H_6O_4$), and particles generated by propane torch & heat gun in the chamber. Good correlation between the CPC3025 and FMPS was observed for the total particle number concentrations in the size range 15 nm to 90 nm. In addition, this paper suggests that photometric mode in water-based CPC3785 could not be used as quantitative of number concentrations for CPC3785.
