CO₂ Grades Explained

A CO₂ grade is a certified minimum purity level with capped limits on specific impurities, set by a governing standard and matched to how the gas will be used. The grade tells you what’s guaranteed to be in the cylinder and, just as importantly, what’s guaranteed to be kept out. Why Does Using the Right …

What Is Food Grade CO₂?

Food grade CO₂ is carbon dioxide purified and tested to a level safe enough to put directly into food and drink. In practice that means at least 99.9% pure, with tight caps on specific contaminants measured down to parts per million and even parts per billion. The number alone isn’t the whole story. What earns …

Helium Grades Explained

Helium grades refer to the purity levels of helium gas, ranging from industrial-grade blends to ultra-high-purity gas used in labs and medical devices. The grade you need depends entirely on what you’re doing with it, and picking the wrong one either wastes money or wrecks your results. Let’s break down what these grades actually mean …

What Gas Is Used for Leak Detection?

Helium is the most widely used gas for leak detection, because it’s inert, non-toxic, non-flammable, and small enough to slip through openings that stop everything else.  A 5% hydrogen, 95% nitrogen “forming gas” blend is the main budget alternative, with nitrogen, sulfur hexafluoride, refrigerant tracers, and plain compressed air covering more specific jobs.  The right …

What Gases Are Used by Pharmaceuticals?

Pharmaceutical manufacturing runs on a handful of core gases: nitrogen, hydrogen, carbon dioxide, oxygen, and argon, with ethylene oxide handling sterilization. They show up at nearly every stage, from synthesizing the active ingredient to packaging the finished dose, and they all have to meet pharmaceutical purity grades before they touch product. WestAir supplies gases to …

2026 Helium Shortage: Why Recovery Will Take Years, Not Weeks

Roughly one-third of global helium supply is offline after March 2026 missile and drone strikes destroyed key production trains at Qatar’s Ras Laffan facility.1 Even when the situation in the Strait of Hormuz fully resolves, the supply damage will take years to repair. U.S. distributors are rationing supply and spot prices have skyrocketed. What’s Happening …

Helium Alternatives: Where They Work and Where They Don’t

Helium has viable substitutes for some applications (welding blends, gas chromatography) with manageable trade-offs, but no real alternative exists for MRI cooling, leak detection, semiconductor production, and a handful of specialty welding and purging jobs. The helium market is one of the most volatile in industrial gas, with prices and availability swinging hard on supply …

Solid vs. Liquid Rocket Propellants: What’s the Difference?

The main difference between solid and liquid rocket propellants is controllability. Solid propellants burn from ignition until depletion without the ability to throttle or stop, while liquid propellants offer precise thrust control through variable fuel and oxidizer flow rates. This fundamental distinction shapes everything from rocket design to mission capability, affecting storage requirements, performance characteristics, …

What Gases Power NASA’s Artemis Rockets?

NASA’s Artemis rockets run primarily on liquid hydrogen (LH₂) and liquid oxygen (LOX), the same propellant combination that powered the Space Shuttle. But propellant is only part of the picture. Helium pressurizes the fuel tanks and purges the lines. Nitrogen keeps ground systems safe and inert. Together, these four gases make every Artemis launch possible. …

How Hot Does Acetylene Burn?

Acetylene burns at approximately 3,480°C (6,300°F) when combined with pure oxygen, producing the hottest flame of any commonly used fuel gas. This extreme temperature makes acetylene the go-to choice for welding, cutting, and metalworking applications where you need serious heat concentrated in a precise location. The flame temperature drops to around 2,400°C (4,350°F) when acetylene …

Is Neon a Noble Gas?

Yes, neon is a noble gas. WestAir supplies neon across California and Arizona. Why Is Neon a Noble Gas? Neon is a noble gas because its outer electron shell is completely full, giving it zero chemical motivation to bond with other elements. Its electron configuration is 1s²2s²2p⁶, meaning all 10 electrons are locked into stable, …

What Is Ethylene Used For?

Ethylene (C₂H₄) is used for plastics and packaging production, commercial fruit ripening, medical device sterilization (as ethylene oxide), antifreeze and coolants, PVC manufacturing, detergents and surfactants, polyester fibers, low-temperature refrigeration, and welding fuel gas, among other industrial applications. WestAir supplies ethylene across California and Arizona. Why Is Ethylene Such a Big Deal? Global ethylene production …
