Argon is preferred to less expensive nitrogen in cases where nitrogen may react with the reagents or apparatus. Argon may be used as the carrier gas in gas chromatography and in electrospray ionization mass spectrometry ; it is the gas of choice for the plasma used in ICP spectroscopy .
The gaseous state of water is lighter than air (density 0.804 g/L at STP, average molecular mass 18.015 g/mol) due to water's low molar mass when compared with typical atmospheric gases such as nitrogen gas (N 2). It is non-flammable and much cheaper than helium. The concept of using steam for lifting is therefore already 200 years old.
The thermal conductivity of argon is 68% of that of air or nitrox, hence its use in drysuit inflation. Using argox 20% would slightly degrade this to 74% of that of air. Argon is far more narcotic (about 2.3 times more) than the cheaper and more readily available nitrogen at depth, so it loses out to nitrogen in all roles as a primary breathing ...
Argon (Ar) is an inert gas that is more narcotic than nitrogen, so is not generally suitable as a diving breathing gas. [30] Argox is used for decompression research. [1] [3] [31] [32] It is sometimes used for dry suit inflation by divers whose primary breathing gas is helium-based, because of argon's good thermal insulation properties. Argon ...
Argon, mixed with nitrogen, is used as a filler gas for incandescent light bulbs. [78] Krypton is used in high-performance light bulbs, which have higher color temperatures and greater efficiency, because it reduces the rate of evaporation of the filament more than argon; halogen lamps , in particular, use krypton mixed with small amounts of ...
Frequently used in mixtures with e.g. nitrogen or air. Nitrogen: N 2: 1.15: 28: 1.251 – – not Often used at high pressure. Does not facilitate combustion. Can be used with 10–20% of SF 6 as a lower-cost alternative to SF 6. Can be used standalone or in combination with CO 2. Non-electron attaching, efficient in slowing electrons. Air: 29 ...
The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [1] [2] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air) [3] and low relative cost.
Trace gases are gases that are present in small amounts within an environment such as a planet's atmosphere.Trace gases in Earth's atmosphere are gases other than nitrogen (78.1%), oxygen (20.9%), and argon (0.934%) which, in combination, make up 99.934% of its atmosphere (not including water vapor).
