Inductively coupled plasma atomic emission spectroscopy

Inductively coupled plasma atomic emission spectroscopy (ICP-AES), also referred to as Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), is a type of emission spectroscopy that uses a plasma (e.g. inductively coupled plasma) to produce excited atoms that emit electromagnetic radiation at a wavelength characteristic of a particular element. The intensity of this emission is indicative of the concentration of the element within the sample.

Applications
Examples of the application of ICP-AES include the determination of metals in wine, arsenic in food, and trace elements bound to proteins.
