Helium is used for many purposes that require some of its unique properties, such as its low boiling point, low density, low solubility, high thermal conductivity, or inertness. Of the 2008 world helium total production of about 32 million kg (193 million standard cubic meters) helium per year, the largest use (about 22% of the total in 2008) is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners. Other major uses (totalling to about 78% of use in 1996) were pressurizing and purging systems, maintenance of controlled atmospheres, and welding. Other uses by category were relatively minor fractions.

Carbon dioxide is a colorless, odorless, non-combustion, non-flammable gas at the standard atmosphere pressure, which is widely used in food industry, oil industry, and chemical industry. Carbon dioxide is a ood additive used as a propellant and acidity regulator in the food industry. Carbon dioxide can be injected into the drink by increasing pressure to have drinks bubbles, and then increase the taste when drinking, such as soft drinks, beer. Liquid and solid carbon dioxide are important refrigerants, especially in the food industry, where they are employed during the transportation and storage of ice cream and other frozen foods. Carbon dioxide has also been widely used as an extinguishing agent in fixed fire protection systems for local application of specific hazards and total flooding of a protected space. Carbon dioxide is used as a welding gas primarily because it is much less expensive than more inert gases such as argon helium. Carbon dioxide is used in the carbon dioxide laser, which is a kind of important resource of industrial lasers. Plants require carbon dioxide to conduct photosynthesis. Carbon dioxide in the form of s often used in the wine making.
