Abstract

An air sampling device employing a virtual impactor which comprises a body section 2, an inlet 3 for allowing air to enter the body section, a first outlet 7 for allowing air to exit the body section towards a collection vessel 14; and a second outlet 12 for allowing air to exit the body section towards a vacuum pump. The inlet, first outlet and second outlet are configured such that when the second outlet is connected to a vacuum pump, a major air flow path is created between the inlet and the second outlet and a minor air flow path is created between the inlet and the first outlet, and airborne particles which enter the device through the inlet follow either the major air flow path or the minor air flow path according to their size. Also described is an apparatus and an automated method for detecting airborne biological particles. The apparatus comprises a virtual impactor collection vessels and means for detecting biological particles.
