Patent ID: 7503229

Claim:
A biobriefcase aerosol collector apparatus for sampling air with an air velocity, collecting particles entrained in the air wherein the particles potentially including bioagents, and capturing the particles in a liquid, the biobriefcase aerosol collector apparatus having improved collection efficiency, comprising: a biobriefcase aerosol collector unit including a fluid bowl, a fluid bowl receiving surface on said fluid bowl, a forcing cone a forcing cone surface on said forcing cone, wherein said forcing cone surface is positioned immediately above said fluid bowl receiving surface, a liquid input that directs the liquid to said fluid bowl receiving surface and produces a liquid surface on the liquid, an air input that directs the air between said fluid bowl receiving surface and said forcing cone surface and provides an air velocity increase so that the air with particles entrained in the air impact said liquid surface on the liquid, and an electrostatic contact connected to the liquid that imparts an electric charge to the liquid electrically charging the liquid, wherein the collection efficiency of the biobriefcase aerosol collector apparatus is improved by electrically charging the liquid.
