Mixed Gases

Mixed gases are a wide and diverse group of products developed for use in specific industries for customized applications. A gas mixture is defined in a molar gas fraction, by percentage, parts per thousand or parts per million. Though gas mixtures are used in many industries, these are common applications in the medical, food and beverage, and welding industries.

The medical industry relies heavily on high-purity specialty gases with a purity of 99.99% for various applications, ranging from anesthesia to MRI machines. High-purity gases are a requirement in the industry, especially when they are used for breathing treatments. Patients can breathe easy with medical-grade mixed gases for respiratory therapy from our PurityPlus certified lab. Heliox (helium and oxygen) treatments are commonly used for the following illnesses: asthma, chronic obstructive pulmonary disease (COPD), bronchiolitis, bronchopulmonary dysplasia and upper airway obstruction. Neonatal and pediatric intensive care units also use Heliox for premature babies and infants with bronchopulmonary dysplasia to support their breathing, so they won’t experience muscle fatigue. It is one of four mixed gases used for this purpose, including nitric oxide, hypoxic gas and carbon dioxide.

Carbon Dioxide and nitrogen play significant roles in food preservation and transport. Both nitrogen and carbon dioxide, sometimes in a mixture, prevent oxidation, which causes unhealthy compounds, unpleasant tastes and awful odors, by displacing oxygen in food packaging. Nitrogen improves freezing and refrigeration techniques, and dry ice (frozen CO2) prevents insect infestation in grains and farm products.

Acetylene has a low moisture content, making it ideal for various welding and heating applications, such as gouging, hardening, bending, straightening, brazing, cutting, cleaning and more. Acetylene and Oxygen combined, create a neutral flame for welding that neither oxidizes nor carburizes. As the hottest burning flame in oxyfuel welding, acetylene is one of the most efficient gases to use. It improves cut quality, increases cutting speed, and reduces oxygen, thus preventing metals from rusting. The automotive and construction industries remain a few of the top industries that still use acetylene gas mixtures.
