520 |a"An aerosol generating system was integrated into a large chamber to regulate three experimental conditions, temperature, relative humidity (RH) and particle concentration during aerosol studies. A commercial heating and cooling unit was used to control temperature. Control of RH was effected by a polymer-based sensing mechanism coupled to a fogging device. Aerosol particle size and numbers were monitored and controlled by a microcomputer-driven detector coupled to an aerosol generator. The system was able to provide precise and reproducible environmental conditions conducive to aerosol studies. Aerosol concentration control was demonstrated over a range of concentrations suitable for different requirements. Under these conditions, a BW simulant aerosol was stable in terms of viability for an extended period of time. As an illustration of the system's potential application, it was used to demonstrate sampling characteristic similarities between a glass fiber filter and a glass impinger. With the features described the system has significant utility in aerosol studies involving threat detection and protection. This system is easily adapted to drive a dry powder disseminator to generate different CBW simulant aerosols. A Canadian patent (No. 1,222,300) has been awarded to part of the system"--abstract.
