Salient Features of AAS and AES:

You know that in atomic spectroscopy, the component present within a sample is converted to gaseous atoms or elementary ions within a procedure known as atomisation that might be brought about through any of the available methods. Absorption of the radiation through the vapourised atoms in the ground state or fluorescence emission or emission of suitably excited state forms the basis of various kinds of atomic spectroscopies. Cooperatively, the atomic spectroscopic methods can be used for the qualitative and quantitative determination of about 70 elements in a wide variety of samples of clinical, biological, and environmental origin. Let us recollect the salient features of the AAS and AES methods before taking up their applications.
