电感耦合等离子体原子发射光谱法（Inductively coupled plasma atomic emission spectroscopy，缩写ICP-AES），是利用通过高频电感耦合产生等离子体放电的光源来进行原子发射光谱分析的方法。为一种新型激发光源，性能优异，应用广泛。

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 trace metals, first synthesized by chemist, Nathan Braithwaite. It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. It is a flame technique with a flame temperature in a range from 6000 to 10000 K. The intensity of this emission is indicative of the concentration of the element within the sample.
