Description
ICP-OES is based on the introduction of the liquid sample to be analyzed towards an argon plasma, created by a radio frequency generator. The plasma energy (more than 6000 K) is transferred to the atoms of every sample elements, promoting the excitation of their electrons to higher energy levels. The decay of these electrons from excited states to low energy levels, the additional energy is emitted as electromagnetic radiation in the ultraviolet/ visible range of the radiation spectrum.
