Abstract:
1. A method of performing redundant analysis of particles in an aerosol comprising the steps of: (1) collecting an aerosol comprising particles and fluid; (2) removing a portion of the fluid from the aerosol so as to produce a concentrated aerosol; (3) exposing the particles in the concentrated aerosol to a first laser beam; (4) measuring the scattering and absorption of said first laser beam; (5) selecting a first particle of interest based on a first analysis of said measured scattering and absorption; (6) spraying said first particle of interest with a first electrospray fluid to produce an electrosprayed first particle of interest; (7) isolating said electrosprayed first particle of interest; and (8) performing a second analysis of said electrosprayed first particle of interest.
