Rare gases, also known as noble gases, are the most inert and unreactive elements known to man. They are found in very low concentrations in the environment (0.001818% neon, 0.000114% krypton and 0.0000087% xenon) and are manufactured by Air Separation Units (ASU). Due to their unique chemical properties, experts have found very novel and interesting applications for them.
Most rare gases are very stable, as such their ionization energy is very high. That makes them very useful as ion beam sources to clean, cut or weld materials. Another property is their unique ability to produce bright light, which may be in the form of a laser (neon/helium laser) or a light source (xenon). Finally, they are very heavy and dense gases, so they are used in propulsion engines or in window insulation.
Air Products offers rare gases and rare gas mixtures in a variety of purities, concentrations and modes of supply around the world thanks to our global network of storage and transfill facilities.
