ABSTRACT:
A method and a device for the treatment of a gas to be analyzed in a gas mixture, including a separation of components from the gas mixture, where the presence of said components is undesirable for performing the analysis. An aerosol filter is employed for the separation of undesired components. A reagent material is admixed to the gas stream, wherein the reagent material forms an aerosol together with the undesired components of the gas mixture. The gas stream passes a reaction path (4) after the entering of the reagent materials. The reaction distance (4) provides a dwelling time for the generation of aerosols in the mixture of gases and the reagent material. The aerosol filter (5) is disposed downstream of the reaction distance (4), which separates the aerosols from the gas stream.
