Chapter 20, Problem 20-18(choose chapter or problem)
MgO prevents premature evaporation of Al in a furnace by maintaining the aluminum as Al2O3. Another type of matrix modifier prevents loss of signal from the atom X that readily forms the molecular carbide XC in a graphite furnace (a source of carbon). For example, adding yttrium to a sample containing barium increases the Ba signal by 30%. The bond dissociation energy of YC is greater than that of BaC. Explain what is happening to increase the Ba signal.
