   This is exactly what is exploited in atomic absorption spectroscopy (AAS for short): 5 By thermal or photochemical excitation of a sample of one or the other metal, individual atoms are induced to emit the respective element- characteristic radiation. This results in an “atomic species-specic lamp” that emits only photons with . element-specic

   Atomic absorption spectrometry Atomic absorption spectrometry (AAS) is an analytical technique that measures the concentrations of elements. Atomic absorption is so sensitive that it can measure down to parts per billion of a gram (µg dm– 3) in a sample. The technique makes use of the wavelengths of light specifically absorbed by an element.
