Abstract: An analyzer for aerosols has a transparent heating chamber in which a mixture of the aerosol to be analyzed and of a dilutent is heated to the emission temperature of the dispersee particles in the aerosol, the dilution being sufficient to produce sequential light pulses from the emitting particles. The pulses of a desired wavelength are transmitted through a filter to a photomultiplier whose output pulses are analyzed in a known manner to obtain data on concentration, size distribution and composition of the dispersed particles.
