1. The benefits of ICP-OES coupling

The first commercial devices to use a rare-gas plasma induced by high-frequency coupling as a means of atomization, ionization and excitation, combined with detection by atomic emission spectrometry, also known as ICP-OES, date back to 1974 [P 2 719] . Thanks to its performance, ease of use and relatively limited number of interferences, this type of coupling is now extremely widespread in laboratories.

If the performance achieved can explain this success, it is essentially due to the very qualities of the ICP source, namely :
