Argon does not react with the filament in a lightbulb even under high temperatures, so is used in lighting and in other cases where diatomic nitrogen is an unsuitable (semi-)inert gas.Argon is perticularly important for the metal industry, being used as an inert gas shield in arc welding and cutting.Argon-37 is produced from the decay of calcium-40, the result of subsurface nuclear explosions. Argon is present in some potassium minerals because of radiactive decay of the isotope potassium-40 This gas is inert and is classified as a simple asphyxiant.Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death.Other uses incude non-reactive blanket in the manufacture of titanium and other reactive elements and as a protective atmosphere for growing silicon and germanium crystals.Argon-39 has been used for a number of applications, primarily ice coring. Argon is also used in technical SCUBA diving to inflate the drysuit, due to its nonreactive, heat isolating effect.The WAAIF is equipped with A MAP215-50 mass spectrometer with a low-blank automated extraction system coupled with a New Wave Nd-YAG dual IR (1064 nm) and UV (216 nm) laser, an electromuliplier detector and Niers source.The ultra-violet laser is capable of high-resolution (up to 10 µm beam size) ablation of any mineral, allowing detailed analysis of individual mineral grains.

For larger aliquot of minerals ( The facility is automated and can be controlled remotely via VNC iphone technology.The effect of simple asphyxiant gases is proportional to the extent to which they diminish the amount (partial pressure) of oxygen in the air that is breathed.The oxygen may be diminished to 75% of it's normal percentage in air before appreciable symptoms develop.Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen .This chemically inert element is colorless and odorless in both its liquid and gaseous forms. This gas is isolated through liquid air fractionation since the atmosphere contains only 0.94% argon.
