A submicron particle, which is too small to be observed in an optical microscope, may form an observable spot on a chemically prepared substrate of the collector. The size of the spot or "Liesegang circle" is related to the aerodynamic diameter of the particle through a magnification factor. This paper presents the experimental results of the study of this factor using sodium chloride aerosol in the size range of 0.5 to 2 pm which has not previously been studied. We calibrated a cylindrical centrifuge with known sized latex particles. A relationship between the aerodynamic diameter and the deposition length is established. From this calibration one can obtain the aerodynamic diameter of particles of the same geometrical size but of different densities. This provides the needed parameter for calculating the magnification factor. © 1980, American Chemical Society. All rights reserved.
