3.5 Helium (He)
With the lowest boiling point, Helium is used in various applications and industries. It serves as a cryogenic agent to cool superconductive magnetic coils in Magnetic Resonance Imaging (MRI) and Nuclear Magnetic Resonance (NMR) Medical equipment. Aside from that, Helium is chemically inert and can be used to create an inert atmosphere for Tungsten Inert Gas (TIG) or Metal Inert Gas (MIG) welding. It is also used for purging, annealing, sputtering, leak checking and etching applications in the Electronics Industry.
