Multiphase models use volume fraction to track the amount of each phase. So you are going to have to convert the concentration to a voluem fraction.

But if you are talking ppm does this imply the stuff is dissolved, not mixed at a microscopic scale? If so, then a multi component or additional variable approach might be more appropriate, rather than multiphase.
