Abstract

Methods and systems employing multiple sensing volumes (50) for electro-optical mass concentration measurement and controlled deliveries of aerosols. Aerosols are transported in a gas flow stream (15). A sensor responsive to particles within a relatively larger sampling volume (156) within the gas flow stream is combined with another sensor responsive to particles within a relatively smaller sampling volume (162) within the gas flow stream.
