Argon N50

Argon N50

Argon N50 is a very pure, inert noble gas with a purity of ≥ 99.999 %. Its chemical unreactivity and ultra-pure quality ensure repeatable results in critical applications such as carrier gas for chromatography, shielding gas for TIG/MIG welding, semiconductor and laser processes.

Argon N50 is a colourless, odourless and tasteless noble gas with a purity of ≥ 99.999 %. Argon makes up about 0,94 % of the atmosphere. It is one of the noble gases known for its chemical inertness – argon does not react easily with other substances. This makes it an excellent shielding gas for processes where unwanted chemical reactions, such as oxidation of metals in welding, need to be prevented.


Argon N50 does not burn or form persistent compounds under normal conditions. Although argon N50 does not conduct electricity normally, it can be ionised by an electric discharge and emit light – a property that is used in lighting technology, for example. Argon is transported and stored as a pressurised gas.
