1-2 Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938

Precision dynamic high-voltage supply for fast, accurate scanning.

Optional dual-polarity high-voltage supply (single polarity negative
supply is standard).

Convenient front-panel design with touch-screen display.

Electronic control of flow, voltage, particle-size, and instrument
functions.

Auto-recovery due to power loss when sampling in SMPS mode.
Applications of the classifier when used in an aerosol generation system to
produce highly monodisperse particles include the following:

Conducting aerosol research, including studies of particle transport,
diffusion, coagulation, nucleation, and condensation.

Performing particle-charge and electrical-mobility studies.

Conducting filter media tests of filter efficiency.

Calibrating particle instrumentation, such as optical particle counters,
by enhancing the monodispersity of polystyrene latex (PSL) or other
aerosols by removing residue particles and multiplets.
Applications of the classifier when used in a TSI SMPS spectrometer to
offer high-resolution sizing of submicrometer particles include the following:

Conducting aerosol research, including nucleation and condensation
studies.

Performing atmospheric and climate studies.

Conducting Nanotechnology research and materials synthesis.

Conducting combustion and engine exhaust studies.

Characterization of sprays, powders, and other generated aerosols.
Applications of the classifier when used
with other TSI particle instrumentation
include the following:

Performing primary size and
concentration calibration of
Condensation Particle Counters when
used with a TSI Model 3068B Aerosol
Electrometer.

Creating small and large changes in
particle size due to coagulation,
evaporation, condensation,
humidification, and chemical reactions
when used in tandem with a second
DMA.

Measure size distributions of solid
nanosize particles in liquids, or
generate monodisperse aerosols with
particle sizes down to a few
nanometers with high concentrations,
when used with a TSI Model 3480
Electrospray Aerosol Generator.
