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.^[1]^[2] The intensity of this emission is indicative of the concentration of the element within the sample.
