Atomic Fluorescence Spectrometry

• Samples need to be atomized
• Procedure:

  • Atoms illuminated w/ a light source to excite atoms --> Excited states
  • Atoms undergo radiative deactivation [Excited --> Ground state]; Release energy
  • Emit characteristic radiation (Fluorescence)
• More sensitive than AAS for SOME elements b/c fluorescence signal have relatively low background (cannot measure absorbance)
