A method and apparatus for evaluating a bioaerosol sample is provided which includes detecting frequency and/or time resolution factors that allow discriminate between a plurality of signals emitted by the bioaerosol to selectively detect biological materials contained in the bioaerosol sample from materials of non-biological origin and potentially associated with a pathogenic bioaerosol.

Method and apparatus for detection of bioaerosols

The invention comprises a material sampling interface that includes one or more inlet manifolds and one or more outlet manifolds and piping running to and from the manifolds. There are rungs connecting the inlet manifold to the outlet manifold. In addition, a bypass rung is positioned between the inlet manifold and the outlet manifold, with a bypass valve positioned on the bypass. Each of the rungs has piping connected to the inlet and outlet manifolds and a removable reservoir connected to the piping. The reservoir includes an internal removable sampler adapted to sample the material. There is an inlet valve connected to the piping between the reservoir and the inlet manifold and an outlet valve connected to the piping between the reservoir and the outlet manifold. The invention is capable of sampling any flowable material including fluids, gases, particles, etc.
