Abstract: A simplified system for air sample collection and analysis for the presence of airborne pathogen is disclosed. An extraction device is used for extracting biomaterial previously deposited on the surface of a capture element of a sampling device, the capture element being of a select cross section and size. The extraction device comprises an upwardly opening head being wider at a top and narrower at a central opening at a bottom. An elongate cavity is attached to the enlarged head at the bottom extending downward from the head and closed at a bottom end to define an interior space, the cavity having a cross section corresponding to the cross section of the capture element and of a slightly larger size than the size of the capture element. An extraction fluid is in the cavity interior space.
