1.Atomic-emission spectroscopy can be used to detect and measure most elements in the periodic table. It finds its greatest utility in metal analysis.
2.Atomic emission spectroscopy requires gas-phase atoms in excited states.
3.The ions and electrons of the plasma absorb the RF energy to maintain a temperture of approximately 8000 K. The distribution of atomic excited-state populations is determined by the temperture and the Boltzmann equation
4.Because the excitation source is general, all atoms are atomized, excited, and produce atomic emission.
