Measurement of mass of aerosol particles

An aerosol particle mass analyzer (APM) which classifies aerosol particles according to their mass has been developed. Mass distributions of aerosol particles can be measured by the APM combined with a particle counting device. Particle mass that can be measured in this way ranges from 3×10-18 g to 2×10-12 g, which partially fills the mass range that is not covered by the existing mass measuring instruments such as mass analyzers and conventional balances. The introduction of the APM has led to various new techniques of evaluating aerosol particle properties such as effective and true densities, porosities, fractal dimensions, and mass concentrations of suspended particulates. In this article, the principle of the APM and its difference from those of other existing instruments of classifying aerosol particles, the significance of measuring mass of aerosol particles, and the course of events before commercialization of the APM has been achieved are described from the viewpoint of "synthesiology."
