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.

By exhaustive we mean that the analyte is completely oxidized or reduced at the working electrode or that it reacts completely with a reagent generated at the working electrode. There are two forms of coulometry: controlled-potential coulometry, in which we apply a constant potential to the electrochemical cell, and controlled-current coulometry, in which we pass a constant current through the electrochemical cell.

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.

It covers direct precipitation and the method of separating analytes already in particulate forms using filtration and extraction techniques. Filtration uses different filters based on the particle size, while extraction involves separating analytes from a matrix using a suitable solvent.
