Argon in Our Atmosphere

We are well aware that the air on Earth is comprised of multiple gases, oxygen and nitrogen being the two main gases.

Nitrogen Tank Blanketing

For most tank containers there is headspace that, left unfilled, can begin the oxidation process for substances that are prone to this occurrence. To keep these substances in their purest state during transportation and storage, high purity, dry nitrogen is used to replace the air that usually occupies the headspace in these tanks.

The History of Industrial Gases

Richard Mansmann, Vice President of Gas Programs of IWDC, explores the intricate history of the Industrial Gas industry.

Packaging for Atmospheric Gases

PurityPlus Specialty Gases carries most of the atmospheric gases needed for a wide range of industries. At PurityPlus we pride ourselves on the accessibility and availability of these gases through our PurityPlus partners that are across North America. This accessibility is only possible if we utilize the correct packaging guidelines for our specialty gas cylinders like oxygen and argon cylinders.

CO2 in the Entertainment Industry

Carbon dioxide (CO2) has been used to amplify special effects in the entertainment industry for a long time. The gas is cooled to a liquid to easily (and economically) achieve special effects like fog and haze. Most have seen haze effects at concerts to emphasize a spotlight or on TV for cloud effects.

Which regulator is best for you?

The two most important variables that will determine whether a single stage or dual stage regulator should be used are droop and supply pressure effect.

The scoop on Liquid Nitrogen Dewars

Liquid Nitrogen is a colorless, odorless, noncorrosive and nonflammable cryogenic liquid that is associated with the specialty gas Nitrogen.

Where has all of the CO2 Gone?

Recently there was one of largest shortages of carbon dioxide throughout Europe. This is the 4th gas shortage in 10 years in Europe.

How is Helium extracted?

Helium is a byproduct of radioactive decay in natural gas. Therefore since natural gas has the most amounts of helium, most specialty gas laboratories will extract Helium via natural gas. There are also small amounts of helium in the air which can also be extracted, however the process for that is expensive and rarely used.

Is Cryotherapy Right for You?

As of late there has been much talk about a new physical therapy treatment known as Cryotherapy. Athletes and entertainers including Lebron James, Mandi Moore and Jessica Alba all attest to the benefits of this fairly new therapy. But what is cryotherapy and why is it receiving seemingly plenty of press?

"Dragons' Breath" Warning

Liquid nitrogen is commonly used in various welding, medical, and food applications. This is an article pointing out a potential liquid nitrogen hazard.

PurityPlus® Argon: The Winemakers’ Specialty Gas of Choice

The consensus of our more than 150 North American PurityPlus Partners is that their wine-producing customers prefer argon because, 1) unlike oxygen, argon doesn’t react with wine to create any negative characteristics; and 2) argon is heavier than oxygen. Its greater density ensures that more of the gas will be in longer contact with the surface of the wine, thus excluding more oxygen (and its deleterious effects) as well as thwarting microbial spoilage.

PurityPlus® EPA Protocol Specialty Gas Mixtures

Industries and municipalities across the United States are still required to measure air pollution emissions and ambient air quality.
