ICP-AES works by the emission of photons from analytes that are brought to an excited state by the use of high-energy plasma. ... When the analyte is excited the electrons try to dissipate the induced energy moving to a ground state of lower energy, in doing this they emit the excess energy in the form of light.

What is ICP-AES analysis?

Inductively coupled plasma atomic emission spectroscopy (ICP-AES) is a method of emission spectroscopy that excites atoms and ions with a plasma, causing it to emit electromagnetic radiation at wavelengths characteristic of a particular element.

What is ICP-AES used for?

Inductively coupled plasma atomic emission spectroscopy (ICP-AES), also referred to as inductively coupled plasma optical emission spectrometry (ICP-OES), is an analytical technique used for the detection of chemical elements.
