How to Reduce Methane Emissions

Methane emissions can be reduced by sealing the leaks and deliberate releases at oil and gas sites, changing digestion and manure handling on farms, and capturing what landfills give off as waste breaks down. Methane breaks down in the atmosphere in about 12 years while carbon dioxide lingers for centuries, so cuts made now show …

Is Propane Flammable?

Yes, propane is flammable—but only in certain situations.  It burns as a vapor, never as a liquid. Even then, it only ignites when the vapor mixes with air inside a narrow band of concentrations.  Every practical decision about storing, moving, and monitoring propane comes back to keeping your building’s air outside that band. What Is …

What Is Methane?

Methane is a colorless, odorless, flammable gas made of one carbon atom bonded to four hydrogen atoms, written CH₄. It’s the simplest hydrocarbon, the first member of the alkane family, and the main component of natural gas. The four hydrogens sit at the corners of a tetrahedron around the carbon, which makes the molecule symmetrical …

What Is Sulfur Hexafluoride Used For?

Sulfur hexafluoride (SF₆) is used mostly as an electrical insulating gas, with smaller roles in eye surgery, ultrasound imaging, semiconductor etching, and leak tracing. Roughly 80% of all SF₆ produced goes to the electric power industry. WestAir supplies sulfur hexafluoride across California and Arizona. What Properties Make Sulfur Hexafluoride Useful? Nearly every SF₆ application comes …

What Is Neon Used For?

Neon is used in signs and lighting, high-voltage indicators, cryogenic refrigeration, deep-sea diving equipment, laser systems, semiconductor manufacturing, and emerging technologies like quantum computing and aerospace. Most people hear “neon” and picture a buzzing bar sign. Fair enough. That’s the famous one. But neon does so much more than that.  WestAir supplies neon across California …

Is Krypton Rare?

Yes, krypton is rare. It makes up about 1.14 parts per million of air by volume, or roughly one krypton atom for every million molecules of air around it. That works out to 0.0001% of the atmosphere. It isn’t the rarest gas on Earth, though. Xenon is scarcer, at about 0.087 parts per million, which …

Why Is Nitrogen Used in the Pharmaceutical Industry?

Nitrogen is used across pharmaceutical manufacturing because it keeps oxygen and moisture away from drugs that degrade on contact with either. It shields reactions, clears equipment, fills the space above a sealed dose, and freezes biological material for storage. This one gas covers all of it, which is why it shows up at nearly every …

How Long Do Neon Signs Last?

Neon signs typically last 8 to 15 years with proper care and maintenance. The signs that hit 15 years aren’t built from magic glass. They’re well-supplied and well-maintained, and both of those things are under your control. WestAir supplies neon across California and Arizona. What Actually Determines a Neon Sign’s Lifespan? Gas purity, electrode quality, …

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 …
