Patent ID: 8545761

Claim:
A sensor device for the detection of a chemical or biological agent comprising: an intake port for an air sample; a mixing chamber connected to the intake port, the mixing chamber containing: at least one storage container, connection tube, and atomizer comprising a liquid or gel detection improvement agent, or at least one mechanical dispersal device comprising a solid detection improvement agent, the at least one of the liquid or gel detection improvement agent and solid detection improvement agent operable to interact with a chemical or biological agent in the air sample, the at least one storage container, connection tube, and atomizer, or at least one mechanical dispersal device connected directly downstream of the intake port and upstream of at least one heating or cooling plate; at least one storage container and wick for the introduction of water or an aromatic solvent into the air sample connected downstream of the at least one storage container, connection tube, and atomizer, or at least one mechanical dispersal device; and at least one detection element selected from the group consisting of a polymer film, a biometric film, or olfactory cells, and an array of polymer or biometric films, each sensitive to a different chemical or biological agent operable to detect a chemical or biological agent in the air sample, the at least one detection element positioned downstream of the at least one storage container and wick; and an exhaust port positioned downstream of the at least one detection element.
