Abstract
An aerosol collecting device adapted for attachment to a chemical vapor detection system is disclosed to include a chamber comprising an inlet with a collecting funnel attached thereto and open to ambient, an outlet, and a through cavity defined therebetween, wherein the outlet is adapted for fluid connection with an input port of the chemical vapor detection system; and a heating element for heating the chamber to a temperature above the boiling point of a target chemical agent of interest in the form of a droplet or aerosol, wherein the chemical agent in the form of a droplet or aerosol is converted into a vapor form as it passes through the cavity from the inlet to the outlet of the chamber, and prior to entering the intake port of the chemical vapor detection system.
