subject: Industrial Gas [print this page] Industrial gas is a group of gases that are commercially manufactured and sold for use in industrial processes. Some Industrial Gas is Argon Gas, Nitrogen Gas, Helium Gas, Hydrogen Gas Mixture Gas, Calibration Gas and more.
Argon Gas :- Argon Gas is monatomic, colorless, odorless, tasteless and nontoxic gas. Together with helium gas, neon gas, krypton gas, xenon gas and radon gas, it constitutes a special group of gases known as the rare, noble or inert gases.
Argon gas is present in the atmosphere at a concentration of 0.934% by volume at the earths surface. Air is the only known source for the production of pure argon gas.
Argon gas is the most commonly occurring of the rare gases.

Nitrogen Gas:- Nitrogen is colorless, odorless, and tasteless gas. It is non flammable and will not support combustion. Atmospheric air contains 78.09% nitrogen; the gas is slightly lighter than air and slightly soluble in water.
Nitrogen condenses at its boiling point , -195c to a colorless and odorless liquid that is lighter than water. When liquid nitrogen is vaporized and then heated to ambient temperature, it absorb a large quantity of heat.
Nitrogen is separated from air, by distillation, absorption of diffusion.
Helium Gas:-he second lightest element, helium is one of our most precious natural resources. It will not combine chemically at any temperature with any other element. It is non-flammable, non-toxic, and non-explosive. Its chemical inertness makes it perfect for a variety of applications.
Helium's most common application is as a shielding gas for arc welding. Because of its high voltage gradient, it transfers more heat to the weld than does argon at the same arc lengths. This added heat is essential for high-speed welding.
Itself a product of billions of years of radioactive decay beneath the earth's surface, helium is not affected by radiation. Radioactive immunity, along with excellent heat transfer makes it an ideal heat transfer agent for gas-cooled nuclear reactor.
Hydrogen Gas:-Hydrogen is colorless, odorless, tasteless, flammable, and non toxic gas at atmospheric temperatures and pressures. The gas burns in air with a pale blue, almost invisible flame. It is the lightest of all gases appropriate of 1/5 as heavy as air, It is manufactured industrially by either electrolysis, of water, steam, reformation, of hydrocarbons or partial oxidation of coal or hydrocarbons.

Calibration Gas:- A calibration gas is defined by homogeneous mixtures of gases with stated composition and certified concentration of each component with guaranteed uncertainty (certified accuracy) associated with the components over a certain period of time. Calibration gases are produced from pure raw materials, with known contents of impurities.
Preparation Tolerance (PT) and Uncertainties.
Preparation Tolerance indicates how close to the ordered concentration we can guarantee the produced concentration. PT varies with concentration level of particular components. Ref. Quality class.
Uncertainties or Certified Accuracy (CA) is our guarantee of maximum deviation from certified values in the actual value.
