Good afternoon everyone! I just can't find drawings or a description of the creation of an apparatus for determining the permeability and selectivity of membranes in relation to gases and gas mixtures. Maybe someone knows where to find this information?
Dear Roman Nosov, the nature of the membrane is not specified! There are standard equipments and procedures for testing membranes selectivity and permeability, such as ASTM. Any home made setup should learn from that. Please check the following links and attached files. My Regards

Hi;
Please check the attached documents; I hope that they are useful for you.
With my best regards
Hi Dear!
For Gas permeation like Particulates PM 2.5 etc, i developed my own cheap type of prototype setup to capture PM 2.5.
That prototype is just a glass tube.
Futhermore, I can guide you just PM me.
Thank you.
