Abstract:
1. A system for characterizing a totality of particles, comprising: a classification apparatus to select a class of the totality of particles having a defined mobility; a first particle counter apparatus positioned in a first path of the system for use in determining total particle concentration of the selected class of particles; a filter apparatus positioned in a second path of the system, wherein the filter apparatus is defined such that particles of the selected class with different morphologies correspond to different penetration levels therethrough; a second particle counter apparatus positioned in the second path for use in determining a filtered particle concentration indicative of particles of the selected class which penetrate the filter apparatus; and a calibrator apparatus configured to determine at least one morphological parameter based on the fraction of particles of the selected class penetrating the filter apparatus, the fraction determined as a function of the total particle concentration and the filtered particle concentration, wherein the at least one morphological parameter comprises at least information about the particles of the selected class penetrating the filter apparatus.
