Spectroscopy based on emission techniques is usually considered more sensitive than techniques based on normal absorption spectroscopy methods. (a) Why is that so if the same number of emitting or absorbing species is involved in the comparison? (b) In many applications, however, Atomic Absorption Spectroscopy can be more sensitive than Atomic Emission Spectroscopy. When can that apply?
