The concentration of calcium in ammonia solution is about 4 to 10 MPM (mole percent metal) (i.e saturation).
I don't understand this term and how to calculate it precisely.
When I applied the same characterization condition and same weight of graphitic materials, graphene (red line) and graphite source (black line) got different intensities but the similar peak...
