In literature:

The inert gas, nitrogen, had been discovered a year or two before.

The only inert and useless gas in an arrangement like this is the nitrogen of the air, which being in large quantities does act as a serious diluent.
"Scientific American Supplement, No. 586, March 26, 1887" by Various
One of the latest is the tungsten arc in an inert gas.
"Artificial Light" by M. Luckiesh
The nitrogen is an inert, odorless gas, and its use in the air seems to be to dilute it, so that man and animals can breathe it.
"Nature's Miracles, Volume 1" by Elisha Gray
The volume of flame, however, is increased by inert gas, and there is a proportionate diminution of the heating effect.

The alloys can be melted under air, vacuum or inert gas, and the range of compositions is virtually unlimited.
Too many people only think of argon as being an inert gas, and they do not take into consideration that it is heavier than air and can be a danger to them when working in their shops.
ALD Vacuum Technologies GmbH (Hanau, Germany) successfully completed pre-acceptance of a 250-kg batch size VIGA35 vacuum induction-melting inert gas atomizer for a specialty materials manufacturer in China.

However, walk into any motorcycle shop and the majority of the time you'll see a Metal Inert Gas (MIG) welder or Tungsten Inert Gas (TIG) welder close by MIG and TIG both fall into the general arc- welding group.

In science:

Benzene (Tm = 279 K, Tb = 353 K) was bought from Sigma Aldrich (99.9% puriss. p.a.), unpacked under inert gas and sealed into a Duran cuvette.

Knudsen experimentally observed that, no matter how an inert gas was injected into a pipeline, the direction in which a molecule rebounds from the pipeline’s solid wall is asymptotically independent of its initial tra jectory.

In contrast to this, SIMPLE modules contain a considerable volume of inert liquid (glycerol) and gas (compressed N2 ) above the active gel, and cannot be recompressed due to the fragility of their glass containers.

This produces a rapid aging of the detector material, leading to gel fractures and a diffusion of the superheated liquid into inert volumes and fracture voids, increasing the pressure inside the module and ultimately leading to gas leaks occasionally able to produce characteristic acoustic signals.
