Nitrous Oxide (N2O) Gas / Laughing Gas
Oxidiser. Colourless and odourless gas. Gas density is heavier than air.
1. Nitrous oxide (also known as "laughing gas") is commonly used as a general anaesthetic in both medical and dental surgeries. To be effective as an anaesthetic, nitrous oxide must be inhaled in relatively high concentrations mixed with air or oxygen. Nitrous oxide may be classified as a medical gas in some geographies and managed according to the relevant regulations.
2. Nitrous oxide serves in industry as a leak detector for vacuum and pressurised enclosures, buried piping, etc.
3. Nitrous oxide is used in calibration mixtures for environmental control.
4. The nitrous oxide-acetylene flame is employed in the laboratory for the analysis of refractory elements such as aluminium, vanadium, titanium and calcium oxides, by flame emission spectrometry. The use of this flame also permits determination of a certain number of trace metals by atomic absorption spectrometry.
5. Nitrous oxide is used as oxidising component in the production of rocket fuels.
6. Nitrous oxide may be used as an aerosol/propellant in various fields:
→ for whipped cream (because it improves the foaming characteristics of the cream), syrups, concentrates of coffee, chocolate and various flavours, sauces for grilled meats, vinaigrette, etc.
→ in pharmaceutical sprays
→ in cosmetics (perfumes, eau de cologne, hair spray, etc.)
→ in household products, paints and varnishes, insecticides
→ in aerosols for use at low temperatures, such as de-icers, engine starting boosters, etc.
