The United States Pharmacopeia (USP) defines absorption spectroscopy as “the measurement of an interaction between electromagnetic radiation and the chemicals, or atoms, of a chemical substance.” Atomic absorption spectroscopy (AAS) has emerged as a powerful analytical technique in estimating various atoms by the measurement of light energy of specific wavelength. Published by Elsevier Ltd. All rights reserved. Atomic absorption spectroscopy and atomic emission spectroscopy is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation by free atoms in the gaseous state. When metals are heated to their boiling point, they vaporize as free atoms, provided that interaction with other elements is prevented, and it is for this reason that atomic absorption spectroscopy in its present form has found its most extensive applications in the analysis of the metallic elements. Spectroscopy - Spectroscopy - Applications: Spectroscopy is used as a tool for studying the structures of atoms and molecules. Atomic Absorption Spectroscopy is an analytical technique used for the qualitative and quantitative determination of the elements present in different samples like food, nanomaterials, biomaterials, forensics, and industrial wastes.
