    INTRODUCTION & THEORY
     Flame emission spectroscopy is so named because of the
     use of a flame to provide the energy of excitation to atoms
     introduced into the flame
     FES technique deals with the examination of the energy
     emitted from a substance when suitably excited.
     It is a well known fact that alkali and alkaline earth metals
     can be detected by flame test.
     All alkali and alkaline earth metal ions give characteristic
     colours in a Bunsen flame.
     The brightness of the flame colour varies with the amount
     of sodium or other metal introduced.
    Emission of such particular radiation by sodium
     or other metal and the correlation of the emission
     intensity with the concentration of the element
     form the basis of FES.
