ARGON

Argon is monatomic, colorless, odorless, tasteless and nontoxic gas. Together with helium, neon, krypton, xenon, and radon, it constitutes a special group of gases known as the rare, noble or inert gases. Argon is present in the atmosphere at a concentration of 0.934% by volume at the earth’s surface. Air is the only known source for the production of pure argon.Argon is the most commonly occurring of the rare gases.

• Plasma arc Cutting & Welding
• Other Market

Ethylene

Ethylene (IUPAC name: ethene) is a gaseous organic compound with the formula C2H4. It is the simplest alkene (older name: olefin from its oil-forming property). Because it contains a carbon-carbon double bond, ethylene is classified as an unsaturated hydrocarbon. Ethylene is widely used in industry and also has a role in biology as a hormon

Uses

• Ethylene shortens the shelf life of many fruits by hastening fruit ripening and floral senescence . Tomatoes , bananas and apples will ripen       faster in the presence of ethylene. Bananas placed next to other fruits will produce enough ethylene to cause accelerated fruit ripening.
• Ethylene will shorten the shelf life of cut flowers and potted plants by accelerating floral senescence and floral abscission
• Flowers and plants which are subjected to stress during shipping, handling, or storage produce ethylene causing a significant reduction in       floral display.
• Flowers affected by ethylene include carnation , geranium , petunia , rose , and many others.
• Ethylene can cause significant economic losses for florists, markets, suppliers, and growers.
• Commercial growers of bromeliads , including pineapple plants, use ethylene to induce flowering.
• Plants can be induced to flower either by treatment with the gas in a chamber, or by placing a banana peel next to the plant in an enclosed       area.

Ethylene Oxide

Ethylene oxide, also called oxirane, is the organic compound with the formula C2H4O. This colorless flammable gas with a faintly sweet odor is the simplest epoxide , a three-membered ring consisting of two carbon and one oxygen atom. Because of its special molecular structure, ethylene oxide easily participates in the addition reaction , opening its cycle, and thus easily polymerizes . Ethylene oxide is isomeric with acetaldehyde . It is a strong poison to humans, showing carcinogenic, mutagenic , irritating and narcotic effects.

Uses

• It is also a common gas-phase disinfectant which is widely used in hospitals to sterilize heat-sensitive tools and equipment.
• Ethylene oxide is industrially produced by direct oxidation of ethylene in the presence of silver catalyst
• It is extremely flammable and explosive and is used as a main component of thermobaric weapons therefore it is commonly handled and       shipped as a refrigerated liquid.

Oxygen

We manufactured qualitative Oxygen cylinders from high strength aluminum alloy. These are of standard finish and are strictly inspected and tested at every stage by our expert quality auditors. These are appreciated for extremely lightweight and portable design made of superior quality aluminum. These are up to 50% lighter than steel cylinders and are easy to handle at emergency stages. Oxygen make combustion possible, And this property account it various industrial applications.

Oxygen is largest volume industrial gas, it is used in following industry:

• Steel Manufacturing Industry.
• Chemical Industry.
• Pulp and Paper Industry.
• Glass Manufacturing.

NITROGEN

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 , -195°c to a colorless and odorless liquid that is lighter than water. When liquid nitrogen is vaporized and than heated to ambient temperature , it absorb a large quantity of heat. Nitrogen is separated from air, by distillation, absorption of diffusion.

APPLICATION OF NITROGEN GASES:

• RAW MATERIAL
• SHRINK FITTING
• INERT GAS
• DE - FLASHING
• INERT GAS SAFETY SYSTEM
• CRYOGENIC GRINDING
• PROTECTION AGAINST FIRE & EXPLOSION
• HUMAN & VETERINARY MEDICINE
• METALLURGICAL INDUSTRY
• GROUND FREEZING

HELIUM

The 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

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.

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. The example below illustrated the PT and CA.
