Helium is a colorless, odorless, and tasteless monoatomic gas with an atomic weight of 4, a density of 1.78 g per 1 at 0°C and 1 atmosphere pressure. After hydrogen, helium is the most abundant element in the universe; these elements are believed to represent 76 and 23 percent, respectively, of all matter in the universe. The earth's atmosphere, however, contains only 5 ppm of helium.
Helium gas is widely used in scientific research, petrochemical, refrigeration, medical, semiconductor, pipeline leak detection, superconducting experiments, metal manufacturing, high-precision welding, optoelectronic products production. It is used to fill balloons, thermometers, electron tubes, wetsuits, atomic reactors and accelerators.
