DETECTION OF AIRBORNE PARTICULATES

摘要

The present disclosure provides method and apparatus for detection of airborne particulates. Liquid droplets comprising reagents capable of reacting with particulates whereby to produce emitted light are introduced to an air flow comprising particulates, whereupon the particulates and liquid droplets agglomerate thereby producing the emitted light. The light is detected by a suitable detector (7), and agglomeration may be enhanced by application of an oscillating electric field (6). The disclosure is particularly concerned with detection of biological particulates.
