How to Store Propane Tanks

Propane tanks must be stored outdoors, upright on flat surfaces, and safe distances from buildings and ignition sources. Indoor storage creates serious explosion risks since propane vapor is heavier than air and pools in enclosed spaces. How to Store Propane Tanks Outside Store propane tanks upright on a flat, stable surface with proper clearances: smaller …

Is Oxygen Reactive?

Yes, oxygen is highly reactive because of its electron configuration, driving it to form chemical bonds with most elements. This reactivity makes oxygen both essential for industrial processes and creates safety risks. WestAir supplies oxygen across California and Arizona. Why Is Oxygen So Reactive? Oxygen is highly reactive because it has six electrons in its …

What Is a Carrier Gas?

A carrier gas is an inert gas that moves sample molecules through an analytical system, serving as the mobile phase in gas chromatography. Without it, your gas chromatography (GC) won’t function—samples would sit in the injection port or stick to the column instead of reaching the detector for analysis. WestAir supplies gas for gas chromatography …

Can You Freeze Liquid Nitrogen?

Yes, you can freeze liquid nitrogen at -210°C (-346°F), but it requires specialized equipment that reaches much lower temperatures than standard storage systems. Your dewars, tanks, and freezers maintain liquid nitrogen around -196°C (-321°F), which keeps it in liquid form during normal operations. Below, you will learn: WestAir supplies nitrogen across California and Arizona. Why Would You …

Is Krypton Rare?

Krypton is one of the rarest gases on Earth, present in our atmosphere at only about 1 part per million (ppm). This scarcity makes it significantly more challenging and expensive to extract compared to other industrial gases. In this guide, we’ll explore why krypton is so rare. You’ll also learn how its limited availability affects …
