[Alembic Pentameter]

I have three chemical samples.  It's unknown if they are identical solutions, solutions of the same substance at different concentrations, or different substances in solution.

Is there a best / ideal way to go about testing to prove which of the above scenarios it is? 

Is there a way to accomplish this with a panel of gc-ms scans?

I assume that the weight ratio being inconsistent by +/-1.25% is enough to rule out 'identical solutions'.
