WebGeneral Description. Helium is a colorless odorless gas. It is lighter than air. It is nonflammable and is only slightly soluble in water. It is chemically inert. When shipped as a liquid it is very cold and will solidify all other gases. Contact with the liquid will cause severe frostbite. Liquid helium is used in cryogenic research and as a ... WebA nitrogen/helium mix provides the following benefits: improved detection. It can detect much smaller leaks due to the size of the test gas molecules. Helium molecules are far smaller than nitrogen molecules and so are better able to pick up small leaks in a refrigeration system. safe and easy to use, inert and non-flammable.
