This chapter describes the Model 3480 Electrospray Aerosol
Generator and gives an overview of how it works.
P r o d u c t D e s c r i p t i o n
The Model 3480 Electrospray Aerosol Generator, shown in
Figure 1-1, generates monodisperse aerosols in the size range of 2
to 100 nanometers. Beginning with a liquid and adding a solute to
form a solution or suspension, the Electrospray converts the
sample to an aerosol by charging the liquid, pushing it through a
capillary, and exerting an electric field at the capillary tip. The
liquid evaporates from the droplets formed at the capillary tip while
the charge on each droplet is reduced by an ionizer.
In addition to the vast combination of solutes that could be used in
the Electrospray to generate aerosols, the user has the ability to
control the liquid flow rate through the capillary, the intensity of
the electric field at the capillary tip, and the amount of time the
aerosol is exposed to the ionizer.
