Principle of Atomic Absorption /Emission Spectroscopy 15.1 ATOMIC EMISSION-THE FLAME TEST When a small amount of a solution of a metal ion is placed in the flame of a Bunsen burner, the flame turns a color that is characteristic of the metal ion. 8. Chemists employ atomic spectrophotometers to determine the identity and/or concentration of a metallic species. Qualitative applications based on the color of flames were used in the smelting of ores as early as 1550 and were more fully developed around 1830 with the observation of atomic spectra generated by flame emission and spark emission. atomic absorption spectroscopy slideshare.

The atomic emission spectroscopy analysis was used to study the process characteristics. Details about flame emission and atomic absorption spectroscopy and comparison between them. ATOMIC EMISSION THEORY The underlying principle of atomic absorption spectroscopy (AAS) is the absorption of energy exclu-sively by ground state atoms while they are in the gaseous form. Atomic Absorption Spectroscopy Guystav Kirchoff and Robert Bunsen first used atomic absorption spectroscopy—along with atomic emission—in 1859 and 1860 as a means for identify atoms in flames and hot gases. This includes atomic absorption spectroscopy and various molecular techniques, such as infrared spectroscopy in that region and nuclear magnetic resonance (NMR) spectroscopy in the radio region.
