Abstract

Aerosol sampling is a complicated problem in aerosol physics. A technique described to monitor continuously the mass concentration of monodisperse test aerosols using a He–Ne laser. Good approximations are possible from Mie theory. The method is fast, accurate, and eliminates the need for precalibration of a standard sampler to monitor aerosol mass concentration over increments of time. It can be used for sampler efficiency measurements and wherever it is desired to monitor test aerosols of spherical droplets continuously, e.g., in studies of the human respiratory system for droplets larger than a few micrometers.
