Abstract: The invention relates to a method for determining the particle size distribution of an aerosol by means of an aerosol measuring device and to an aerosol measuring device. Aerosol particles of the aerosol flowing through the measuring cell are illuminated in the measuring cell by a light beam. The scattered light is picked up by a detector, so that light signals of the aerosol particles can be detected spectroscopically in terms of intensity. From this, a size distribution of the light signals that is representative of a particle size distribution is produced. A known standard particle size distribution of dry aerosol particles is adapted to the measured particle size distribution, so that moisture influences are eliminated from the measured particle size distribution in this way.
