Difference between Atomic emissions and absorption
Atomic emissions |
Atomic absorption |
Valence electron In higher energy atomic orbital returns to lower energy Orbital there an atomic emission occurs.
|
The theory of Atomic absorption is based on absorption of light and on the free metallic ions. |
It is an analytical tool used to determine and quantify the composition of elements of material. | Atomic absorption can be use in qualitative and quantitative analysis. |
Atomic emission work by forcing a sample material to high energy level by using separate energy source. | Atomic absorption consist of three parts light source ,
Frame atomizer system and detector. |
Wavelength of light are emitted from the sample material’s atom which is recorded and the wavelength used to determine the composition of the sample material. | It use electromagnetic wavelength coming from light source. |
Example of atomic emission is :-
When indium is inserted into flame the flames become blue this phenomenon allow element to identify their atomic emission. |
Example of atomic Absorption :-
Light source, atomization |
