Abstract: The invention relates to a process for the separation of charged aerosols, in which the aerosol is, first of all, separated in a collector electrode, which can be flowed through under the effect of a space charge. For the production of a high electrical potential, electrical charges of the aerosol to be separated are subsequently collected on the collector electrode. Finally, the residual aerosol exiting from the collector electrode is guided through the separation zone at high field intensity. In accordance with the invention, the invention also relates to a device for the implementation of the above-stated process.

Abstract: A device for the selective determination of the quantity of oil mist includes an impactor (1) with a micronozzle (4) for dispensing a predetermined volume of a gas to be tested, a baffle plate (5) arranged downstream of the micronozzle (4) for depositing oil particles. A window (7) is provided on the side of the baffle plate (5) facing away from the micronozzle (4).
