Helium is an essential element in modern chemistry. Liquid helium chills the superconducting magnets inside NMR spectrometers, for example, and blankets of the inert gas can protect air-sensitive compounds. Now the fate of one of the world’s main sources of the gas hangs in the balance and the global helium market faces a period of turbulence that could send prices soaring.
