Atomic absorption spectroscopy is reviewed especially as to the effect of developments in the past few years on analytical applications. Sources and sampling devices are given special attention. Atomic absorption, flame emission, and atomic fluorescence are compared as to their detection limits and their applicability to analysis. It is shown that the three methods are in many ways complementary rather than competing. The potentialities of resonance spectroscopy are examined and instrument systems utilizing resonance methods are described.
