LIQUID AEROSOLS
DRY POWDERS
The Collison Nebulizers shown were developed in cooperation with the noted Aerosol and Industrial Hygiene Specialist,
Robert Gussman of BGI, Waltham, MA. The Result of a
Combination of Interests: Excellence in Toxicology and Industrial
Hygiene.
Suitable for use with precious liquids, these units are modified to use multiple jets (up to 6)
which can be plugged by screws, to selectively
generate aerosol. The unit may be ordered in
horizontal or vertical discharge models. Flange type connectors are standard, which allows attachment to extension tubes, vortex
diluters, isokinetic sampling blocks and other innovative generation
systems.
This enlargement clearly shows the small volume represented by
the aerosol generation chamber and its associated reservoir.
The replenishing fluid enters via the central column from a pump
or gravity fed Luer-type connector.

I
n this cutaway view that the precious fluids well is clearly
visible. Total volume in this chamber is less that one milliliter.
Since it is continuously fillable, there is minimal waste of
precious fluids.
