Helium - Wikipedia

Although it is rare on Earth, helium is the second most abundant element in the known Universe, constituting 23% of its baryonic mass. Only hydrogen is more abundant. The vast majority of helium was formed by Big Bang nucleosynthesis one to three minutes after the Big Bang. As such, measurements of its abundance contribute to cosmological models. In stars, it is formed by the nuclear fusion of hydrogen in proton-proton chain reactions and the CNO cycle, part of stellar nucleosynthesis.

Helium concentrations in United States wells

However, helium concentrations as low as 0.04 can be economic if gas is chilled and purified to meet specifications as liquefied natural gas (National Research Council, 2010). It is important to note that there might be several gas samples from different wells in a given reservoir or formation, hence the concentration values reported for each ...

Helium dilution technique - Wikipedia

The helium dilution technique is the way of measuring the functional residual capacity of the lungs (the volume left in the lungs after normal expiration).. This technique is a closed-circuit system where a spirometer is filled with a mixture of helium (He) and oxygen. The amount of He in the spirometer is known at the beginning of the test (concentration × volume = amount).
