Flame photometer

1.Name of the Instrument: Flame photometer

2.Working Principle : The flame photometer works on the principle of flame emission spectroscopy. When a solution containing alkali or alkaline earth metal ions is aspirated into a flame, the atoms become excited. As these excited atoms return to their ground state, they emit light at characteristic wavelengths. The intensity of emitted light is directly proportional to the concentration of the element.
