Abstract
Direct viewing of the particles by stereomicroscopic methods has many advantages for rapid determination of the important parameters characterizing an aerosol. An equipment is described whereby particles down to 0.05 microns diameter can be studied using a stereoultramicroscope. The 3D view allows an estimate of the average distance apart and hence the number per unit volume. There are no wall effects, since the volume in the field of view is well separated from the boundaries of the cell used. State of aggregation is immediately evident and electrical state can be seen by the behaviour of the particles in a field and followed as it changes with time. Cine films (16 mm) or still photographs can be taken.
