1. 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, 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 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,
a fan that brings the air into said biobriefcase aerosol collector unit, and
a virtual impactor 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 impacts said liquid surface on the liquid, wherein the particles potentially including bioagents become captured in the liquid.
