Working of atomic absorption spectroscopy is quite simple. When a ground state atom collides with light of an apt wavelength,
the atom will absorb the light and gets excited. The aim here is to measure the quantity of light absorbed at resonant wavelength
when it passes through a atom cluster. The increase in the amount of light absorption will be proportional to the increase in the quantity of atoms.
The quantity of analyte material will be calculated by measuring absorbed light quantity.
The atom cloud required for measuring atomic absorption will be generated by exposing the sample to thermal energy and the flame.
The majority of atoms will stay in the ground state when exposed to appropriate flame conditions and can absorb
light emitted from the source lamp at a particular wavelength.
