In this section we consider three popular sources for generating atomic emission: flames, inductively coupled plasmas, and direct current plasmas.

The historical development of AES is highlighted, with applications evolving from flame and spark techniques to plasma sources. AES is suitable for multielemental analysis and involves equipment like atomic emission spectrometers using flames or plasmas.

Atomic emission occurs when a valence electron in a higher energy atomic orbital returns to a lower energy atomic orbital. The emission consists of a series of discrete lines at wavelengths corresponding to the difference in energy between two atomic orbitals.
