Summary

The modification of the dynamic method suggested permits determining the diffusion coefficient of an aerosol from two concentration measurements (Z v ) at the exit of a diffusion battery with different air-flows instead of measuring the concentration (Z) at the entrance and that (Z v ) at the exit as originally employed.

Zusammenfassung

Die vorgeschlagene Modifikation der dynamischen Methode gestattet die Bestimmung des Diffusionskoeffizienten eines Aerosols aus zwei Konzentrationsmessungen (Z v ) am Ausgange der Diffusionbatterie mit verschiedenen Luftstromgeschwindigkeiten anstatt der Messung der Konzentrationen am Eingang (Z) und Ausgang (Z v ), wie in der ursprünglichen, Methode benützt.
