A method and device for collecting airborne particulate samples comprising vacuum air intake tube(s) onto the distal end of each of which is connected a regulating nozzle that is covered by the well reservoir of a capture vessel. Ambient air is directed to impact the interior surfaces of a single or multi-reservoir capture vessel. Each such well reservoir may include additional collector media and can be fitted with a filter screen. A plurality of said intake tubes may also be assembled and automated for programmable sample times and duration through a manifold in order to service a standard well tray which provides for higher collection efficiencies. In situ pathogen detection is possible by inclusion of nucleic acid specific dyes or probes in the media and/or by attachment of an excitation light, radiation detector, or fluorometer device(s) focused on the internal surfaces of a semi-translucent well reservoir.
