Thermal Aerosol Generator 5D

1. Introduction
The ATI 5D Thermal Aerosol Generator uses a heating element to vaporize liquid
reagent. The unit then expels the vapor using inert gas, which rapidly cools,
generating aerosol.
Condensation (quenching) happens at the 5D output collar, before the vapor comes
into contact with enough oxygen to combust. This quenching requirement makes
an air-gap necessary between the aerosol output and the system the aerosol is
entering for testing. The 5D has built-in air quenching holes behind the output
collar, which shall not be covered or restricted.
