Types of samples:

Atomic emission spectrometry (AES) and Atomic absorption spectrophotometry (AAS) are being widely used for the elemental analysis of geological, biological, environmental, industrial and other types of samples.

The salient features of AAS and AES along with a comparative account of the two techniques, followed by the sample preparation for the analytical determination by these technique have been recapitulated in this unit to give an overall picture of the two techniques. The significance and principles of some important typical applications of AAS and AES in diverse areas such as biological sample, environmental samples, and industrial samples have also been discussed.
