In atom absorption spectroscopy, why is it important for the cathode tube to be the same metal as that being determined?

  • chemistry -

    The energy being emitted by the cathode tube will be absorbed by the metal for which the sample is being analyzed. Other elements will not absorb at that wavelength.
