Helium - General Information Helium is a non-toxic, non-flammable, colorless, odorless inert gas which has unique properties such as low boiling point, low density and high thermic conductivity. Helium is used to fill balloons because it is lighter than air and causes balloons to float.
The Helium Gateway is the world's first crypto miner that uses radio waves instead of power-hungry computations. Built to power a decentralized machine network, the Helium Gateway introduces a fair, eco-friendly method to generate tokens. Coming Q4 2018 – Join the Waitlist.

Helium occurs in natural gas, in radioactive ores, and in small amounts in the atmosphere. It has the lowest boiling point of any substance and is the second most abundant element in the universe. Helium is used to provide lift for balloons and blimps and to create artificial air that will not react chemically.

Bulk Deliveries/Storage Systems - Liquid or gas bulk deliveries and storage systems provide a safe, reliable supply option for high-purity helium. Global helium distribution network Because helium is a rare element, efficient distribution and storage for reliable backup are just as important as access to sources to ensure your supply.
The element helium was discovered in 1895 by Sir William Ramsay. The name comes from the Greek word "helios," which means "sun." It is a colorless gas that is lighter than air and consists of two protons and two neutrons.
Helium gas can be supplied in a variety of purity grades, mixtures, and cylinder sizes Typical Helium Recovery System For reference information about cylinders, conversions, and safety, visit our Publications Library .
Helium-3 was thought to be a radioactive isotope until it was also found in samples of natural helium, which is mostly helium-4, taken both from the terrestrial atmosphere and from natural gas wells. Other than protium (ordinary hydrogen ), helium-3 is the only stable isotope of …

Helium is the second lightest and second most common element in the universe.It is at the top of the noble gas group in the periodic table. Characteristics and Properties At room temperature helium is an odorless, tasteless, colorless gas.
Helium gas is colorless, tasteless, odorless, non-toxic and inert. Most helium gas is extracted from natural gas deposits. Radioactive emissions from α decay are helium nuclei. Helium is the second least reactive noble gas after neon. Inhaling helium gas can raise the pitch of a person's voice.
At Praxair, we deliver gas and liquid helium (He) in a variety of purities up to 99.999%. Explore the chart below to view the spec sheets and safety data sheets for our pure helium products and a few of our popular welding mixtures.
Helium is a chemical element with the symbol He and atomic number 2. Helium is a colorless, tasteless and odorless gas. Helium is the second most common element in the Universe (after hydrogen), making up around 24% of its mass.
Helium-neon gas lasers are used to scan barcodes in supermarket checkouts. A new use for helium is a helium-ion microscope that gives better image resolution than a scanning electron microscope. Biological role. Helium has no …
Helium gas is an unreactive, colourless, and odourless monoatomic gas. Helium is available in pressurised tanks. Helium is the second most abundant element in the universe after hydrogen. α-particles are doubly ionised helium atoms, He 2+.
Helium History. The discovery of Helium dates back to August 18th, 1868 with a French astronomer by the name of, Pierre Janssen. At this time he was in India watching an eclipse of the Sun and noticed a strange yellow wavelength.
(Helium has been accumulating for many millions of years in a few natural gas fields, therefore we can currently extract more each year than is being created by uranium and thorium decay.) 11. Helium was discovered in the Sun's atmosphere before it …
For use only by or under the supervision of a licensed practitioner who is experienced in the use and administration of Helium and is familiar with the indications, effects, dosages methods, and frequency and duration of administration, and with the hazards, contraindications and side effects, and the precautions to be taken.
For other applications, argon cover gas might be substituted for helium, as is done in countries where helium gas is expensive, but there would be some loss in productivity. Laser Processing Processing with carbon dioxide (CO 2 ) lasers is a growing activity in the United States.
