Measurement system for the multidimensional aerosol characterization

Method of characterizing the total amount of particles (318) are proposed. The method in particular can be used to characterize the aerosol microparticles or nanoparticles. The method includes the following steps. In a) the classification step, the selected class of the total amount, selected class of the particles (318), the step of having the mobility d In b) the counting step, the step number N of the particles (318) of the selected class is determined. In c) the charge determination step, the step of charge Q of the particles (318) of the selected class is determined. In d) evaluation step, at least one morphological parameter, the charge Q, is determined from the number N, and the mobility d .FIELD 1
