GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROSCOPY 

The graphite furnace is an electrothermal atomiser system that can produce temperatures as high as 3000°C. The heated graphite furnace provides the thermal energy to break chemical bonds within the sample held in a graphite tube, and produce free ground state atoms.

Ground-state atoms then are capable of absorbing energy, in the form of light, and are elevated to an excited state. The amount of light energy absorbed increases as the concentration of the selected element increases.
