Abstract

The particle size distribution of a polystyrene latex has been
determined using a new light-scattering photometer which measures
the scattered radiance as .a function of scattering angle of single
aerosolized particles as they are levitated in a laser beam. The
results are in agreement with those obtained by conventional light
scattering and by electron microscopy. In addition to the main population,
two classes of smaller particles were observed. This single
particle light-scattering technique offers the possibility of analyzing
broader size distributions than heretofore amenable to light scattering
and has the added advantage of not requiring any a priori
assumptions about the form of the particle size distribution.
