Flame Photometry

A Flame Photometer is an instrument used to analyse inorganic chemicals to determine the concentration of certain metal ions (mainly are sodium, potassium, calcium, lithium, Barium). It is defined as the measurement of intensity of the light emitted when any alkali or earth metal is introduced into the flame. Because of the emission of radiation, it is also known as flame emission spectroscopy. Flame photometry is based on mearsurement of intensity of light emitted when a metal is introduced into the flame – the wavelength of the colour tells what the metal is (qualitative), the color’s intensity tells us how much element present (quantitative).
