Abstract:
A particle-measuring apparatus ( 1 ) for determining the particle mass concentration in aerosols having different properties has an aerosol photometer ( 2 ), by means of which a photometer measured value, which is dependent on the particle mass concentration in the aerosol, can be measured, and an evaluation unit ( 9 ), into which photometer measured values measured by the aerosol photometer ( 2 ) can be input and in which the input photometer measured values can be processed in order to output corrected particle mass concentration values. In order to provide a particle-measuring apparatus or a corresponding method that can be used to determine the particle mass concentration in a mobile manner, for example in a vehicle, or with different aerosol properties in different regions, it is proposed that respective calibration factors are stored in a memory ( 17 ) of the evaluation unit ( 9 ) for different aerosols, in that the particle-measuring apparatus ( 1 ) has an optical particle counter ( 10 ), by means of which the particle size distribution of aerosols can be detected and can be input into the evaluation unit ( 9 ) of the particle-measuring apparatus ( 1 ), in that the particle size distribution currently detected by the optical particle counter ( 10 ) can be compared in the evaluation unit ( 9 ) with particle size distributions, stored in the memory ( 17 ) of the evaluation unit ( 9 ), of the different aerosols associated with the stored calibration factors, and in that, by means of the evaluation unit ( 9 ), the stored calibration factor associated with the aerosol for which the particle size distribution has the most matches with the particle size distribution currently detected by the optical particle counter ( 10 ) can be selected for a determination of the particle mass concentration of the aerosol currently being measured.
