Inductively coupled plasma emission spectrometry (ICP-OES) is one of the most important instrumental methods of elemental analysis. This method can be used to measure elements with detection limits of ppm in various samples such as soil, water, metals, ceramics and organic samples. The basis of this method is the excitation of electrons of different elements in an environment called plasma and the emission of light after the electronic comfort state, and due to its versatility and reproducibility, it is possible to obtain results with high precision and accuracy. One of the important advantages of this method is its high repeatability and the possibility of measuring several elements at the same time.

ICP-OES has the ability to identify elements including heavy metals such as Hg, Pb, Zn, Cu, Cd, Cr and alkaline and alkaline earth elements such as Li, Na, K, Ca, Mg in a wide range of concentrations with a detection limit of ppb and… at the same time.
