Why argon is used in ICP OES?
Argon is important for OES Spectrometers analyzing light elements such as Carbon, Phosphorous, Sulfur, and Nitrogen. These elements are below 200 nanometers (nm) in wavelength and the argon allows the optic of a spectrometer to see from 200 and below.
Can you mix argon and nitrogen?
With argon-nitrogen gas mixture, the Ti interlayer becomes stronger and thus can provide increased support to the TiB2 coating, leading to enhanced adhesion strength.
How dense is Argon?

Why argon gas is used in ICP-MS?
Inductively coupled plasma (ICP) reaches much higher temperatures than a combustion flame (>8000 K). Argon plasmas are conventionally used to provide a high-temperature, high-stability excitation source in ICPAES.
What is the purge gas in ICP-OES?
Argon is used as the ICP torch gas with the Optima 8000. Nitrogen is recommended for the optical purge gas, although argon can be used as well.
How is argon used in manufacturing?
Manufacturing Industry Argon is used popularly within welding and casting industries, especially in the making of specialty alloys and manufacturing titanium. It is also used as a shield gas during arc welding, seeing as it protects the metal that’s being worked on from oxygen.
Is argon used in steel manufacturing?
Argon oxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminum.
What are the gases used in gas welding?
Gases used in welding and cutting processes include: shielding gases such as carbon dioxide, argon, helium, etc. fuel gases such as acetylene, propane, butane, etc. oxygen, used with fuel gases and also in small amounts in some shielding gas mixtures.
Which gas is not used in gas welding?
Firstly: Propane cannot be used for Gas Welding. When acetylene burns in oxygen, it creates a reducing zone that cleans the steel surface. Propane do not have a reducing zone like acetylene and can hence not be used for Gas Welding.
How is argon gas made?
Argon is industrially extracted from liquid air in a cryogenic air separation unit by means of fractional distillation. When nitrogen gas present in the atmosphere is heated using hot calcium or magnesium, a nitride is formed leaving behind small amount of argon as an impurity.
What is the use of argon gas?
Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.
