en.wikipedia.org/wiki/Helium

Helium is a commonly used carrier gas for gas chromatography. The age of rocks and minerals that contain uranium and thorium can be estimated by measuring the level of helium with a process known as helium dating. Helium at low temperatures is used in cryogenics, and in certain cryogenics applications.

Helium is the second most abundant element in the universe, but here on earth, it's rather rare. Most people guess that we extract helium from the air, but actually we dig it out of the ground. Helium can be found in certain parts of the world, notably in Texas, as a minor component in some sources of natural gas.

Helium is one of the most common elements in the universe. It is called a noble gas because it doesn’t chemically interact with elements. Its atomic number is 2 and the weight is 4.002. In its natural state, it doesn’t have any smell, taste or color. Common Uses of Helium Evidence shows that the human voice can be changed with a bit of helium.

When we think of uses for helium, most everyone immediately thinks of party balloons, blimps, and high-pitched voices. However, the uses for helium go far beyond just a few novelties. (Never inhale helium, by the way. It can kill you.) In fact, without helium, we may have never had our supermarket checkouts, iPhones, or even the ability to ...

Although not used directly as rocket fuel, helium is used to clean the fuel tanks of the liquid hydrogen and oxygen that are used as fuel. Knowing that helium is inert allows the space program to trust that it won’t react or combust with any oxygen that happens to remain in the tank. 7. Microscopes

Uses of Helium. The largest use of helium is in cryogenics. It is used in the field because of its low boiling point and low density. It is mainly used to cool superconducting magnets in MRI scanners. Helium is also commonly used to pressurize and purge systems of unwanted gases.

Liquid helium is an important cryogenic material and is used to study superconductivity and to create superconductive magnets. The Department of Energy's Jefferson Lab uses large amounts of liquid helium to operate its superconductive electron accelerator. Helium is an inert gas and does not easily combine with other elements.

Thus, it is uncertain how much helium is actually used each year for welding and whether this decline is the result of a decline in the use of helium in welding, a decline in other uses reported as welding, or a change in how the other uses are reported. The two uses of helium to be discussed in this section are arc welding and laser welding.

Helium is put into balloons to help float Helium is easily detected in minute quantites, and has a very small "molecule". So helium is also used for checking vacum and other enclosures for leaks.

The U.S. military's submarine detectors use liquid helium to clean up noisy signals, and the U.S. Air Force uses helium in experiments on superconductors as a power source, according to the ...
