Abrégé
(EN) The invention relates to a method for determining the particle size distribution of an aerosol by means of an aerosol measuring device and an aerosol measuring device. Aerosol particles of the aerosol flowing through a measuring cell are illuminated with a light beam in the measuring cell. The scattered light is picked up by a detector such that light signals of the aerosol particles are recorded spectroscopically in terms of intensity. From this, a size distribution of the light signals that represents a particle size distribution is generated. A known standard particle size distribution of dry aerosol particles is adapted to the measured particle size distribution such that the measured particle size distribution is adjusted by moisture influences.
(ZH) 本发明涉及一种借助气溶胶测量设备来确定气溶胶的粒径分布的方法和气溶胶测量设备。在测量单元中利用光束照射流过测量单元的气溶胶的气溶胶颗粒。由检测器记录散射光,从而通过光谱按照强度检测气溶胶颗粒的光信号。由此得到表示粒径分布的光信号的大小分布。将干燥的气溶胶颗粒的已知的标准粒径分布匹配于测量的粒径分布,从而这样消除对测量的粒径分布的湿度影响。
