Nitrous Oxide Supplier to Indianapolis A colorless, sweet-tasting, oxidizing gas, Nitrous Oxide (N2O) is used commercially quite often in Indianapolis, and American Welding & Gas, Inc. is pleased to offer it from PurityPlus®. Nitrous Oxide was originally synthesized in 1772 by Joseph Priestly, who brought iron filings into contact with a nitric acid drip. That may seem about as simple a process as one could devise, but an even simpler technique for producing greater amounts of N2O was developed under the auspices of Humphry Davy in the late 1700s. It involves the application of carefully administered heat to ammonium nitrate, which effects its decompostion into Nitrous Oxide and water. Most N₂O production makes use of this process, either directly or by a similar means of production using urea and a combination of sulfuric and nitric acids. Nitrous Oxide is employed as an anesthetic, as a leak-detection gas, and as an oxidizing agent. It frequently shows up also as a propellant in aerosol cans for the pharmaceutical and food-and-beverage industries, most commonly in commercially marketed whipped-cream dispensers. N₂O has further application as a specialty oxidizing flame-support gas in atomic absorption (AA) instrumentation for metal analysis. When mixed with particular perfluorinated hydrocarbons, it makes an excellent propellant/oxidizer for some special-application rocket guidance systems. When its purity is driven to the highest levels (around 99.995+%, Nitrous Oxide is used with some frequency in semiconductor fabrication.
