摘要： A method and apparatus for sorting and performing redundant analysis of particles in an aerosol is disclosed. Redundant analysis reduces the possibility of false positive analyses, which is advantageous in the art. The apparatus may comprise an aerosol concentrator, an optical particle analyzer, an electrosprayer and a charged particle analyzer. A method according to the invention may comprise delivering a concentrated aerosol stream to an optical particle analyzer; analyzing each particle of interest and selectively triggering an electrosprayer to electrospray each particle of interest; adding a charge to the particle, which is then moved by electrostatic forces to a charged particle analyzer; and performing a second, redundant analysis of each charged particle collected on the charged particle analyzer to confirm the identity of the particle of interest. The apparatus and method may also be adapted to perform redundant analysis of disguised particles that are coated to disguise their payload.
