Pure Gases

Labgaz offers a variety of pure gases that are required throughout the various research institutions, pharmaceutical, petrochemical and related industries. Typical applications include chromatography carrier gases, continuous analyzer gases and sample purging.

Labgaz offers many types of pure gases available in containers ranging from small, non-refillable cylinders to cryogenic liquid containers.  Bulk gas delivery is available within Labgaz service. Pure gas quality is assured by Labgaz strict adherence to ISO 9001:2000 Quality Management Standard( view certificate).

Our most common pure gases are detailed in the links below.  If you require a different gas, contact your local Labgaz store for pricing and availability

  • Acetylene

    Acetylene is a highly combustible gas composed of carbon and hydrogen. It is used as a fuel gas in the oxyacetylene welding process. An alternate definition is a fuel gas comprising two carbon atoms and two hydrogen atoms, C2H2. If acetylene is compressed on its own, it can lead to a highly exothermic reaction. For this reason, acetylene is supplied dissolved in acetone. Acetylene cylinders are made of a porous material capable of storing the acetone-acetylene solution.

  • Air, Compressed

    Compressed air is a mixture of Nitrogen and Oxygen filled in high pressure cylinders. While Air does not burn, it does supply oxygen necessary for combustion. Compressed air is used in both industrial and medical applications.

  • Argon

    Argon is a colorless and odorless monatomic gas with a density relative to air of 1.38. Its chemical symbol is Ar. Argon's most useful property is its total inertness to all substances at all temperatures and pressures. It is most widely used as shielding gas in arc welding.

  • Carbon Dioxide

    Carbon Dioxide (CO2) is a nonflammable, colorless, odorless, non-toxic and slightly acidic gas. CO2 is a simple asphyxiant (lack of oxygen) and is approximately one and one-half times heavier than air.

    Carbon dioxide has unique characteristics as it can exist in three forms: gas, liquid and solid (dry ice). CO2 can be filled one container at a time by weight into cylinders or liquid cans. These containers can be modified to allow either gaseous or liquid use of carbon dioxide. Carbon dioxide is typically stored in refrigerated liquid or vacuum jacketed tanks. These characteristics lend themselves to CO2's multitude of uses.

    At Norco, our carbon dioxide is available in the following sizes (designated as lbs.): 2.5, 5, 10, 20, 35, 50, 75, 100, 450 (GP 55)

  • Helium (He) is an inert gas and a member of the rare gas family. At room temperature and atmospheric pressure, helium is a colorless, odorless and tasteless. Gaseous helium is commonly shipped in cylinders at pressures between 2,000 to 2,600 psi. In liquid form, helium is shipped in vacuum insulated non-metal (aluminum) dewars at very low pressure. Helium is: a simple asphyxiant, colorless, odorless, tasteless, non-toxic, nonflammable, and lighter than air.

    Cryogenic helium is used extensively in laboratories and MRI units at hospitals. Helium is also used extensively in the welding industry as an inert shielding gas for arc welding. It is also used in mixtures of neon and argon for electronic tubes and the familiar neon signs.

    Helium is also used in laboratories as a leak detector, as a temperature standard, and as a carrier gas in gas chromatography . Mixtures of helium and oxygen are used as a diving gas for divers working under high pressures (created during low-depth diving).

  • Hydrogen

    Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen. Hydrogen is a commercially important element. Large amounts of hydrogen are combined with nitrogen from the air to produce ammonia (NH3) through a process called the Haber process. Hydrogen is also added to fats and oils, such as peanut oil, through a process called hydrogenation. Liquid hydrogen is used in the study of superconductors and, when combined with liquid oxygen, makes an excellent rocket fuel.

  • Nitrous Oxide

    Nitrous Oxide (N2O) is a clear, colorless, oxidizing liquefied gas with a slightly sweet odor. The product is stable and inert at room temperature. The U. S. Department of Transportation classifies nitrous oxide as a non-flammable gas. Nitrous Oxide will support combustion and can detonate at temperatures in excess of 650° C (1202° F).
    Over 80 percent of the Nitrous Oxide market is used as an analgesic property in the medicine/dentist industry.
