What are inert gases and what are they used for?
The noble gases, also called rare gases, include six gases: helium, neon, argon, krypton, xenon and radon. Their volume in the air is 0.94 per cent for argon, 0.0018 per cent for neon, 0.0005 per cent for helium, 0.00011 per cent for krypton, 0.000009 per cent for xenon, and radon is a gas that is radioactive. They are called rare gases bec...

Helium-3 Helium-4 separation technology
The helium-3 isotope is a rare isotope of helium that is found in very small amounts in the atmosphere, typically only 0.000137 per cent of helium. However, the helium-3 isotope has a wide range of applications, including magnetic resonance imaging, nuclear magnetic resonance and superconductivity. Two isotopes of helium exist in nature,...

The filling of sulphur hexafluoride gas prohibits the ent...
Moisture is a condition for the production of toxic substances from Sulphur Hexafluoride equipment. If the water content of Sulphur Hexafluoride gas exceeds the specified water content, when its water content changes, it can condense on solid insulating surfaces, making the surfaces wet, and then the surface discharge voltage o...

Usually does not seem to be a very good understanding of some of the gas, in fact, he played a big role in life, although in life we are not scientists, nor researchers, are positive contact with these gases, but he developed things are applied to all aspects of our lives, can play an indirect contact process. 1. The formation of xenon...

Why would anyone use deuterium gas? What are the applicat...
Deuterium gas, a mysterious substance, not only plays an important role in scientific research, but also has a wide range of applications. So what is deuterium gas? First of all, we need to understand what deuterium is. Deuterium is a stable isotope, which means that unlike the hydrogen atoms in ordinary water molecules, it...

Pressurized liquefaction separates carbon monoxide and hy...
Pressurised liquefaction [carbon monoxide is at -19O°C; hydrogen is liquefied at -253°C] so that the carbon monoxide is liquefied while the hydrogen remains in the gaseous state. This is the best way to separate hydrogen from carbon monoxide. Alternatively, Pressure Swing Adsorption (PSA) is used. Pressure Swing Adsorption is a new type of...

3.Helium application in laser cutting Laser cutting is a high-precision cutting technology commonly used to cut metallic and non-metallic materials. During the laser cutting process, a gas is used to purge the cutting area to prevent the formation of oxides and to reduce laser scatter. Helium is an ideal purge gas because it is...

Neon is used for deep-sea diving to help breathe.
As light helium gases (e.g. helium, neon) have little or no anaesthetic effect on the human body, they can be used instead of nitrogen to formulate breathing gas mixtures for deep sea diving operations. Neon-oxygen or helium-oxygen breathing gas mixtures can effectively reduce the physical exertion of divers due to their lower density and ...
