Abstract
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. TRUNCATED
