A Technique for Measuring Broad Size Ranges of Aerosol Particles by the Laser Beam Scattering Method Combined with Condensation Nuclei [Translated]†

Abstract

In order to determine broad ranges of particle size distribution, a new measuring method combined both light scattering and electrostatic separation-condensation nuclei is experimentally investigated. From the experiments, it is confirmed that by using a sensitive optical particle counter connected to a digital computer system, the particle size range of 10 nm to 10 µm in diameter is adequately measurable. Furthermore, using the same criteria to count the number of particles over the entire size range, this method is found to be remarkably applicable as a practical means of more accurate measurement.† This report was originally printed in J.
