Balloons: As already mentioned, the most common use for helium gas is for decorative balloons. However, this has since stretched to helium for weather balloons and airships.
Medical Applications: Helium gas can be used for respiratory ailments to treat conditions such as asthma and emphysema. Liquid helium also has medical purpose as it is used as a cooling medium for magnets and process use in MRI scanners and NMR spectrometers
Car/Vehicles: As helium is a very unreactive element, it is used to detect leaks in car air-conditioning systems. It is also used to inflate airbags as helium can diffuse quicker than most unreactive gases.
1. Croygenics
Helium is used as a super coolant for cryogenic applications such as Magnet Resonance Imaging (MRI), Nuclear Magnetic Resonance (NMR) spectroscopy, particle accelerators, Large Hadron Collider, Superconducting Quantum Interference Device (SQUID), Electron Spin Resonance spectroscopy (ESR), Superconducting Magnetic Energy Storage (SMES), magnetohydrodynamic superconducting generators, power transmission, magnetic levitation transport, superconducting sensors, mass spectrometers, superconducting magnets, strong-field magnetic separator, toroidal field superconducting magnets for fusion reactors and other cryogenic research. Helium cools low-temperature superconducting materials and low-temperature superconducting magnets to a temperature close to absolute zero, so that the electrical resistance of superconductors drops abruptly to zero. The very low electrical resistance of superconductors enables to create more powerful magnetic fields. In the case of MRI equipment in hospitals the more powerful magnetic field yields greater detail in the radiological image scans. Helium is used as super coolant, because helium has the lowest melting and boiling points of any element and helium does not solidify at atmospheric pressure and 0 K and helium is chemically inert. Furthermore helium is superfluid below 2.2 Kelvin. Untill now the unique property superfluidity is not exploited in any industrial application. Helium as super coolant cannot be substituted in cryogenic applications, if temperatures below 17 Kelvin are required.
Helium is used for leak detection, because helium has the smallest molecular size and it is likewise a monatomic molecule. Therefore helium passes easily through the smallest leaks. During leak detection an object is filled with helium and in case of a leak a helium mass spectrometer will detect where the leak is located. Helium provides for detecting leaks in rockets, fuel tanks, heat exchanges, gas lines, various electronic devices, television tubes and other manufactured components. Helium for leak detection was first applied during the Manhattan Project to find leak in the uranium enrichment plants. Helium for leak detection can be substituted by hydrogen or nitrogen or a mixture of hydrogen and nitrogen.
Helium is applied as carrier gas and purging gas for gas chromatography, because helium is chemically inert and high purity. Chromatography is a collective term used for laboratory techniques to separate mixtures. Chromatographs are widely used for qualitative and quantitative analysis in processes and laboratories. As carrier gas helium can be substituted by hydrogen or nitrogen.
