Kleine Geschichte der ICP-OES • Vorstellung des ersten ICP Anfang 1960 •1975. Thermo Fisher Scientifi Inductively coupled plasma optical emission spectroscopy (ICP-OES) is the technique of choice for many different applications, including those in the environmental, metallurgical, geological, petrochemical, pharmaceutical, materials, and food safety arenas. It can be applied to varying sample types such as aqueous and organic liquids and solids. Some of these sample types need specific sample.
reported that ICP-OES is significantly affected by physi-cal interference and spectral interference, but relatively less affected by the other two types of interference(1). However, ionization interference is known to affect ICP-OES when the coexisting elements are easily ionizable elements, such as alkali metals. This is particularly a large problem in axial view, since the emissions spectra.

ICP-OES designs are required to use additional gas flows such as a shear gas, to optimize their plasma interface. This can increase instrument running costs, interfere with light transmission or requires expensive accessories such as air compressors to be purchased with the instrument.
