ICP atomic emission spectrometry identifies the composition and content of elements in a substance by measuring the wavelength and intensity of characteristic spectra emitted by gaseous atoms or ions of each chemical element after excitation. It is suitable for trace element analysis, applicable to most metals and a small number of non-metals such as silicon, phosphorus, and sulfur.
