How to include the saturation concentration of a species in a domain?

Hi,
I am currently using the transport of diluted species physics to look at oxygen diffusion in my model. It is composed of different domains that should have different oxygen saturation levels. How can I include these saturation levels in my model? Is there a way to set a maximum concentration level in a domain?
I have already tried to force a concentration on a boundary using the concentration node with an "if" statement, but that seems to mess up my simulation.
Thanks in advance, Guillaume

I'm not sure if this works but can you try setting the diffusivity coefficient to zero if the concentration exceeds the saturation value in each subdomain? For example, if the diffisivity coefficint in domain 1 is 1e-9 m^2/s and the saturation coefficint is 7 mol/m3 you may use:
D = 1e-9 * (c<7)
