Atomic absorption spec-troscopy requires that the atoms be in their ground state. At high temperatures ionization may occur, reducing the number of ground state atoms and therefore reducing the absorbance. This especially occurs in the nitrous oxide-acetylene flame, and some of the more easily ionized elements include calcium, strontium and barium.
