Abstract
A system and method for sampling constituents in air including counting particles in the air to be sampled; collecting samples of accumulated particles; measuring UV response of a sample of accumulated particles only if the particle count exceeds a predetermined threshold; measuring IR response of that sample; and indicating a threat alarm if the IR response matches that of a target within a predetermined threshold.
