Product Name:

It is the natural atmosphere of the earth. It consists of a mixture gaseous elements containing 21% oxygen and 78% nitrogen. It can be separated into its components. Synthesized air is produced by combining pure oxygen and nitrogen. Dry air is non-corrosive.
Product Name:

It is the most abundant member in the rare gas family, which consists of other members, such as helium, neon, krypton, and xenon. It is colorless, odorless, tasteless and nontoxic. It is slightly soluble in water. It has been increasingly used in many applications, especially in metallurgical progress. It is blown into furnaces and stir the molten metal and flushing other gases from the melt, mainly in the production of stainless steel. It is also widely used as a shielding atmosphere in welding.
Product Name:

It is a synthesis gas generally produced from the reaction of water with calcium carbide. A colorless flammable gas, it is slightly than air and has strong garlic-like odour. It’s unstable and highly combustible and produce very hot flame when combined with oxygen to over 3000℃. Acetylene is highly soluble in acetone and DMF(dimethyl formamide)
Product Name:

It is the second lightest element after hydrogen. It is one of the rare gases of the atmosphere. It’s chemically inert, colorless, odorless and tasteless. Liquid helium is the only known substance that could remain liquid form at temperature near absolute zero. Hence it has an unique use as a refrigerant in cryogenics. Helium is generally obtained from natural gas fields.
Product Name:
carbon dioxide

It is non-flammable, colorless, odorless and slightly acidic, with its inert quality; it’s suitable for prevention and suppression of combustion and oxidization. It is a dominant refrigerant or cooling agent in the industry. Solid CO2 is used in the food industry for chilling and freezing. It is also widely used in the fighting applications.
