Abstract
The invention relates to a process for the determination of the concentration of particle collectives of different sizes contained in an aerosol stream, said process having the following features: a) that the aerosol stream is divided into three substreams one after the other in such a way that increasingly larger particle collectives are contained in the substreams, starting with the first substream, and thus the concentration of the large particle is raised, b) that in the substreams, the concentration is measured at intervals in time by means of concentration measuring devices based on each concentration enrichment, and c) that the different particle collectives contained in said three substreams are trapped separately.
