The Agilent 5110 ICP-OES (Inductively Coupled Plasma - Optical Emission Spectrometry) is installed and active at Guilan University Central Laboratory. This machine can simultaneously detect over 63 chemical elements.

"In the ICP-OES, plasma is generated at the end of a quarts torch by a cooled induction coil through which a high-frequency alternate current flows. As a consequence, an alternate magnetic field is induced, which accelerates electrons into a circular trajectory. Due to the collision between the argon atom and the electrons, ionization occurs, giving rise to a stable plasma. The plasma is extremely hot, 6000-7000 K. In the induction zone, it can even reach 10000 K. In the torch, desolvation, atomization, and ionization of the sample takes place. Due to the thermic energy taken up by the electrons, they reach a higher "excited" state. When the electrons drop back to ground level, energy is liberated as light (photons). Each element has its characteristic emission spectrum that is measured with a spectrometer. The light intensity on the wavelength is measured and calculated."

Its vast elemental spectrum, low chemical interference, and maximum sensitivity has made the ICO-OES one of the most important and frequent machine-based techniques for elemental analysis. Thus, it serves different fields, such as materials science and environmental chemistry, and in some cases, it replaced other techniques such as AAS (Atomic Absorption Spectroscopy).

This machine is the only active and advanced, of its kind, in the Guilan Province. The Guilan University Central Laboratory, which is a standard laboratory, Customs laboratory, and trusted DOE (Department of Environment) laboratory, is ready to offer examination services to the country's Customs, industries, knowledge-based enterprises, faculty members, academics, students, and other universities.
