Choosing the proper module: TDS vs. TCS

Hello, Thank you for reading this thread.

I want to model the diffusion of a solute through a pipe filled with water from a compartment with an aqueous saturated solute solution. The only material inside the pipe is water, and the water is not flowing (no convection involved). Since the chamber holding the saturated solution has a high concentration (77 mg/ml) and I am only modeling the diffusion of one solute in one solvent, I am not sure whether I should use the TDS or TCS. Based on the COMSOL manual, it looks like I should use the TDS, but the high concentration involved in this problem makes me think I should include the TCS somehow.

What do you suggest?
