Abstract:
1. A device for characterising, separating and/or eliminating suspended particles in a carrier gas of an aerosol wherein the aerosol contains solid suspended particles and volatile suspended particles, comprising: a gas supply and a gas discharge, further comprising heating means for heating the aerosol to a temperature at which volatile suspended particles evaporate, but the solid suspended particles are unaffected, a dilution unit for diluting the aerosol with a dilution gas, wherein, referring to a flow direction of the aerosol, the dilution unit is arranged upstream of the heating means, and further comprising a measuring unit arranged downstream of the dilution unit and the heating unit, the measuring unit being capable of measuring either the characteristics of or the quantity of the unaffected solid suspended particles, or both, remaining in the aerosol downstream of the dilution unit and the heating unit.
