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.

Claim (Index 4):
A method for determining the particle mass concentration in aerosols having different properties, wherein, by means of an aerosol photometer ( 2 ), a photometer measured value dependent on the particle mass concentration in the aerosol is measured and the photometer measured values are processed in order to output corrected particle mass concentration values, characterized in that respective calibration factors (K 1 , K 2 , K 3 , K 4 ) are stored for different aerosols, in that the particle size distribution of aerosols is detected by means of an optical particle counter ( 10 ), in that the particle size distribution currently detected by the optical particle counter ( 10 ) is compared with stored particle size distributions of the different aerosols associated with the stored calibration factors (K 1 , K 2 , K 3 , K 4 ), and in that the stored calibration factor (K 1 , K 2 , K 3 , K 4 ) associated with the aerosol for which the particle size distribution has the most matches with the particle size distribution currently being detected by the optical particle counter ( 10 ) is selected for a determination of the particle mass concentration of the aerosol currently being measured.
