Abstract

Two experimental concepts are presented, as well as some interesting experimental results. The Field and Laboratory Emission Cell (FLEC) is an integral part in both experiments. Gypsum board in form of plaster board is studied as a porous model material. From an experimental point of view, the one-flow system is easier to set up. A comparison of the diffusion coefficients show reasonable agreement. A clear correlation of the calculated diffusion coefficient with the boiling point and the molecular area of the corresponding halogenated aromatic compound can be observed. A dependence of steady-state diffusion coefficients on the concentration is noticeable. The mass flow across the test specimen does not differ much among different compounds, and can be surprisingly fast.
