Raphael:

Can you please explain how your cell works in more detail? As far as I can understand, there is an inlet tube where 2 species c and c2 enter the cell and an outlet tube where they leave the cell. Once they are inside the cell, they interact with a circular sensor which only allows "c" to pass through and not c2. How is this selection done? Are you applying any external current or an electric field?

Also, if you have the electrochemistry module, I suggest you use the Tertiary current distribution which will take care of all these modules together.

Sri.
