Measurement system for the multidimensional aerosol characterization
A method is proposed for characterizing a totality of particles. The method can be used in particular for characterizing microparticular or nanoparticular aerosols. The method comprises the following steps: a) in a classification step, a class of the totality is selected, wherein the particles of th...

description | A method is proposed for characterizing a totality of particles. The method can be used in particular for characterizing microparticular or nanoparticular aerosols. The method comprises the following steps: a) in a classification step, a class of the totality is selected, wherein the particles of the selected class have a prespecified mobility dm; b) in a counting step, a number N of the particles of the selected class is determined; c) in a charge determination step, a charge Q of the particles of the selected class is determined; and d) in an evaluation step, at least one morphological parameter is determined from the charge Q, the number N and the mobility dm, wherein the morphological parameter comprises at least one item of information about an agglomerate state of the particles. |
