A Concentric Aerosol Spectrometer

Abstract

A concentric aerosol spectrometer utilizing centrifugal sedimentation to separate the particles is described. The spectrometer utilizes a new type of inlet system that permits introduction of the sample into the deposition channel through a short inlet from an excess of dusty air. Calibration curves for several rotational speeds and deposition channel flow rates are given. The inlet losses and the resolution of the instrument are discussed.
