available from TSI. The Model 3480 Electrospray
Aerosol Generator produces stable, monodisperse, submicrometer
aerosol in the range from less than 3 to
greater than 100 nanometers. It achieves such small
diameters by moving a conductive liquid solution or
suspension through a capillary and applying an electrical
field to the liquid at the capillary tip. The electrical
field draws the liquid from the tip into a conical jet
from which ultrafine charged droplets are emitted. Air
and CO2 are merged with the droplets, and the liquid
evaporates while the charge is neutralized by an ionizer.
The result is a neutralized, monodisperse aerosol
that is practically free of solvent residue.
A
APPLICATIONS
The successful use of the electrospray method to
generate monodisperse aerosol has been documented in
many publications. Although the basic principles are
well understood, many of the fine details explaining
how different operating parameters affect the electrospray
method remain to be discovered. Known applications
for this instrument include:
? Instrument calibration
? Studies of nano-aerosols
? Deposition of nanoparticles onto surfaces
? Aerosol analysis in the macromolecular and submicrometer
range
? Dispersion of nanometer-sized powders for research
applications
? Research involving parameters that influence the
electrospray process
