Solution
It should be emphasized that the aerosol coming out of the
Atomizer is wet and has a high electrostatic charge. Until the
particles are completely dry, the particle size changes. A diffusion
dryer, discussed in Chapter 4, is highly recommended.
Generating Oil Aerosol
Oil aerosol from solutes such as dioctyl phthalate (DOP), olive oil,
and oleic acid can be generated either with or without alcohol as
the solvent. Use the nonrecirculation mode of operation when using
alcohol as the solvent (see Chapter 3). To obtain constant output,
provide sufficient damping and mixing in the aerosol stream. You
can construct a simple damping chamber with a 1-liter bottle,
similar to the reservoir bottle used in the recirculation mode. Feed
the aerosol to the bottom of the bottle through one fitting and
remove the aerosol through the other.
