Helium is abundant in the sun's atmosphere, and at trace levels in the Earth's atmosphere. Helium is an extremely light gas and is therefore very volatile. It is colourless, odourless, non-flammable, completely inert and cannot sustain life.
Helium is used in hospitals and facilities as a cooling fluid for your MRI, NMR or EPR magnets and to calibrate analytical instruments.
Air Liquide Healthcare’s ALPHAGAZ™ offer is designed for you needs, providing an easy to use system that allows you to select which product you need for your applications.
