Atomic Absorption Spectroscopy vs ICP-MS... which one is best... Is there any difference between ICP-AES and ICP-OES ? Dear Sir. Over 10 million scientific documents at your fingertips. So, the key difference between atomic absorption and atomic emission is that atomic absorption describes how atoms absorb certain wavelengths from the electromagnetic radiation whereas atomic emission describes how atoms emit … They arise when the absorption line of an interfering species either overlaps or lies so close to the analyte absorption line that resolution by the monochromator becomes impossible. While AAS quantifies the absorption of electromagnetic radiation by well-separated neutral atoms, AES measures emission of radiation from atoms in excited states. In: White W.M. 192.185.83.97.
