Atomic Absorption

Atomic Absorption. Where g = degeneracy. Lines are broadened by two effects:. Doppler Collisional Operating conditions for lamp are chosen so that the Doppler broadening in the lamp (low P, few collisions) is less than the Doppler and collisional broadening in the flame or furnace.

Atomic Absorption Spectroscopy

Atomic Absorption Spectroscopy. Atomic absorption spectroscopy is based on the same principle as the flame test used in qualitative analysis. The high temperature of the flame excites a valence electron to a higher-energy orbital.
