ABSTRACT:
An apparatus for collecting airborne particles and microorganisms by injecting them into a swirling air flow from where they are removed onto a dry surface, a surface coated with an adhesive material or a surface wetted by a liquid that is swirled onto that surface from a liquid reservoir below. The swirling air motion and the aerosol injection into it are achieved by pushing or drawing the airborne particles and microorganisms through one or more nozzles that are directed at an angle towards the collection surface. Each entire nozzle or only its exit section are aligned along the axis of aerosol flow injection into the swirling air flow. The apparatus consists of one piece or of three main components that are assembled to form one unit and are comprised of one inlet section, one nozzle section, and one collection vessel.
