GD-OES Spectrometry

Plasma optical emission spectroscopy (GD-OES) is an advanced analytical technique that allows elemental analysis and characterization of materials. Álava Ingenieros offers Horiba Scientific’s technology for GD-OES spectrometers that provide fast and accurate results in various industrial and research applications.

What is GD-OES spectrometry?
Plasma optical emission spectroscopy (GD-OES) uses an electrical discharge in a low-pressure gas, usually argon (Ar), to produce a plasma to analyze the composition of materials. This process is performed between two electrodes in contact, in vacuum and in contact with the argon.

Basic principles of GD-OES

• Ionization of argon: the electrical discharge ionizes the argon, creating a plasma that generates a current flow between the electrodes.
• Sample atomization: argon ions impact the sample surface, atomizing its components.
• Excitation and ionization: the atoms of the sample are excited and ionized, emitting photons at characteristic wavelengths.
• Photon detection: these photons are detected and analyzed to identify and quantify the elements present in the sample.

Advantages of GD-OES Spectrometry

• High depth resolution: allows investigation from a few nm to more than 150 microns deep, with a depth resolution of up to 1 nm.
• Speed and ease of use: it is an extremely fast and easy to handle technique, suitable for routine and research analysis.
• Simultaneous analysis: allows the simultaneous analysis of all the elements of interest, which improves the efficiency of the analytical process.
