Abstract:
1. An aerosol-particle analyzer (APA) for measuring the amount of an analyte in particles in a gas comprising: (a) an analysis liquid chosen to be suitable for collecting particles for further analysis; (b) a droplet generator, having a droplet generator output, that generates a droplet of the analysis liquid (DAL) and ejects it out of said droplet generator output when signaled to do so; (c) a particle-droplet-collision subsystem (PDCS) consisting of an aerosol particle detector enclosed in a gas-tight container, having a droplet input connected to the droplet generator output, a particle input, a PDCS-DAL output, and a vacuum connection that: (d) a vacuum pump connected to the PDCS vacuum connection that draws the gas and particles into the PDCS, where the gas and any particles not combined with the DAL are then evacuated; (e) a droplet analysis system that accepts the DAL ejected from the PDCS through a vacuum tight connection and measures the amount of analyte in the CDAL.
