What Makes Specialty Gases So Special? - Air Source Industries

Specialty gasses are used in a variety of industrial, scientific, and medical applications. But what makes them so special? In this article, we’ll provide an overview of specialty gasses and explain why they are so important.

What Are Specialty Gases?

Specialty gasses are gasses that have been specially formulated for use in industrial processes, medical treatment, or scientific research. These gasses often consist of specific mixtures of two or more common atmospheric gasses, such as oxygen and nitrogen. The exact composition of these mixtures can vary greatly depending on the application for which they are intended. For example, a gas specifically designed for welding may contain trace amounts of hydrocarbons, while a gas designed for pharmaceutical manufacturing may contain higher levels of carbon dioxide.

The Benefits of Specialty Gases

One of the main benefits of using specialty gasses is their purity. These gases are produced under strict quality control guidelines to ensure that they contain no impurities or contaminants that could affect the product or application. By creating gasses with carefully controlled compositions, processes can be carried out with greater precision and accuracy than would otherwise be possible. This makes them much safer than regular air, which contains water vapor, dust particles, and other compounds.

In addition, the use of specialty gasses can help minimize waste by ensuring that only the necessary amount of gas is used in a process or procedure.

In industries where safety is paramount—such as aviation or automotive engineering—specialty gasses can also help reduce risks by maintaining optimal pressure levels in aircraft cabins or fuel tanks. Specialty gas mixtures can also be used to create hypoxic (low oxygen) training environments for athletes who wish to increase their red blood cell production without the risks associated with altitude training.

Safety Considerations

When working with specialty gases, it’s important to understand the safety considerations associated with them. As these gasses contain potentially hazardous elements, it’s important to take all necessary precautions when handling them or storing them at your facility. Additionally, you should always make sure that your staff is properly trained in the safe use of these gasses before allowing them to handle any specialized equipment that utilizes them.

Conclusion

Specialty gasses have become increasingly important over the years as industrial processes become more complex and demand precision beyond what is achievable when using regular atmospheric air alone. By providing carefully formulated gasses capable of meeting specific requirements, specialty gasses can help ensure maximum efficiency and safety in a range of industries, from aerospace engineering to medical research. With their versatility and reliability, it’s no wonder why specialty gasses are so popular among industrial workers and scientists alike!

Have you ever gone deep-sea diving, had an MRI or used a cell ? Then you have high purity specialty gases to thank for that.

What are Specialty Gases?

High purity gases like Helium, Nitrogen, or Oxygen, as well as other valuable gases, are what many refer to as specialty gases. Specialty gases are rare or ultra-high purity gases that consist of one single gas or a gas mixture containing components at high concentrations. They are closely scrutinized for purity from the percent range down to part per billion and sometimes even part per trillion (99.995 percent min. purity to 99.% ) as they are used in a wide range of applications from medical and pharmaceutical fields, to manufacturing plants, refineries, research labs, and nuclear power plants. 

Why Use Specialty Gases?

Many different industries require compressed gases with higher levels of purity and more precise accuracies than your standard industrial or medical gas. The benefit of higher purity specialty gases is that they provide the unique properties that can help improve yields, optimize performance and lower costs due to the less contamination and lower concentrations of impurities that can cause problems down the road.  

Why are Specialty Gases so special?

The high level of purity, compared to the same gas at an industrial or medical purity, is one of the differentiators that make a specialty gas special.

Helium

Helium for example, at 99. percent purity or grade 5.5 (five 9s and a 5) it is used for fiber optics like the ones cell towers use and grade 6 (six 9s) is the closest you can get to 100 percent pure helium and is used in the manufacturing of semiconductor chips, or most of us know them as the tiny wafers that pack the power behind our smart phones, computers, tablets, televisions, and more. It’s also used in research laboratories, laser cutting, and MRI machines.  

Nitrogen

Nitrogen is another common specialty gas that can be used for several different purposes, ranging from lab research to manufacturing of electronic devices. For example, the pharmaceutical industry requires ultra-high purity or UHP nitrogen (99.999 percent min. purity) for applications where shield gas is needed for certain medicines. UHP Nitrogen is also commonly used as a carrier gas, purge gas or detector gas for a range of analytical equipment.

Oxygen

When you think of oxygen, most people picture a friend or family member hooked up to an oxygen tank to help them breathe. But oxygen at its purest form is used for so many different things.  The United States Pharmacopoeia (USP) standards require medical grade oxygen to be no less than 99.0 percent purity and not more than 99.6 purity. It is not necessary for humans to breathe 100% oxygen. Whereas the purity and grade of oxygen gas in fields such as industrial, cryogenic, food processing, scientific and laboratories is crucial. Grade 5.0 oxygen (99.999 percent pure) is sometimes referred to as research grade.  This is the highest purity of oxygen manufactured in the US and is typically found in research facilities. Its non-research uses include welding of titanium and titanium alloys for the nuclear or aerospace industry as well as glass and ceramic production and other such industry applications.
