"Inductively Coupled Plasma-Optical Emission spectroscopy" (ICP-OES) often also called ICP-AES (Inductively Coupled Plasma-Atomic Emission spectroscopy) is an atomic spectrometric detection technique used for the quantitative determination of elemental concentrations. The technique is using the Inductively coupled plasma (ICP) as an atomizer and excitation source, that due to its very high temperature in the range of 7000-8000K efficiently desolvates, vaporizes, excites, and atomizes samples introduced as gases, vapors or aerosols.
