A brief description on the operation of the Atomic Absorption Spectrometer. Please note: There is an error in the explanation from 3:10 to 3:30. The correct explanation is:"Photons from the hollow cathode lamp are absorbed in the flame by the atoms of the element being examined. These atoms then emit identical photons but in a random direction so that the number going straight through from the lamp to the detector is reduced. The random emitted photons are not detected except for those which happen to be emitted in the original direction by chance." We apologise for this and will rectify this as soon as possible.
