Gas mixture flow simulation

Hi everybody,
Gas 1 is flowing in my geometry (a round pipe) and I want to inject gas 2 into the flow.
My idea was to assign both gases to the same geometry (using pipe flow module twice) and then use the transport of concentrated species module to adjust the molar fraction of gases in a way to tell COMSOL that initially there was just gas 1 and then an x molar fraction of gas 2 is injected into the flow.
My question is: Is this a right way to deal with the problem and how to tell COMSOL to assign different materials (gas 1 or gas 2) to the same domain dependent on the physics?
Thanks.
