PreservativeĪrgon can extend the shelf life of food by displacing oxygen and preventing aerial oxidation and hydrolysis. A man died in 1984 from asphyxiation due to argon at the construction site of an oil pipe in Alaska. It is difficult to detect and creates concern for argon tank leakage into confined spaces. It can also act as a preservative as it replaces oxygen within a bird.Īrgon can be dangerous to humans in closed areas. This makes it useful to asphyxiate birds as a more humane form of slaughter. Argon Applications in Today’s World What is Argon Used For? Poultry IndustryĪrgon is 38% denser than air and displaces oxygen near the ground. Argon shares similar properties with its group. Other noble gasses include helium, neon, krypton, xenon, and radon. Argon’s electron configuration is 3s2 3p6. Argon is a noble gas with a full valence electron shell, making it unreactive.Īrgon has an electronegativity of 0 (Pauling Scale). This element is the third most abundant gas in Earth’s atmosphere. Argon glows a violet and lilac color in a gas discharge tube.Īrgon, atomic symbol Ar, has an atomic number of 18, and lies in group 18, on the periodic table, below neon and to the right of chlorine.Scientific research uses argon to search for dark matter.The atmospheres of Mars and Mercury contain argon.Argon was the first noble gas to be discovered.Here is a new study on the effects of inhaled argon on brain injuries in mice. Argon is being researched as a cheaper alternative to xenon in the treatment of brain injuries.Blue neon lights actually contain argon.They used to be preserved by helium, however, it was replaced because it would leak from the case and require replacement. The American National Archives preserve the Declaration of Independence and the Constitution with argon.The word argon is derived from a Greek word meaning “lazy” and “inactive.”.Argon is twice as abundant as water vapor and over 20 times as abundant as carbon dioxide.It is commonly used for industrial purposes, in scientific research, and as a preservative. It is the most common noble gas and is chemically inert. Results were consistent with those obtained from the rotational temperature derived from simulations of N 2 (2nd positive system) rovibrational band.The element argon is colorless, odorless, nonflammable, and nontoxic. For validation purposes, it was applied to a microwave-induced plasma jet working at different operational conditions. The method allows the simultaneous determination of the gas temperature. In this work, we propose a new spectroscopic method to measure the amount of air in argon non-thermal (including cold atmospheric) plasma jets through the collisional broadening of Ar I 840.86 and Ar I 842.46 nm emission lines. But, in this kind of reactor, unknown amounts of air enter the plasma region depending on the experimental conditions, changing the chemistry in them, and eventually their effects. Because they run in the open atmosphere, they generate copious amounts of reactive oxygen and nitrogen species, which play an outstanding role in their biological action. Cold atmospheric argon plasma jets have shown to be very promising in medicine and they are being currently used for therapeutical uses such as the healing of wounds or the treatment of tumors.
