Nitrogen (N2)

Nitrogen is essential to life on Earth. It is a component of all proteins, and it can be found in all living systems. Nitrogen compounds are present in organic materials, foods, fertilizers, explosives, and poisons. Nitrogen is crucial to life, but in excess it can...
Argon gas (Ar)

Argon gas (Ar)

Argon gas (Ar)Argon is a colorless, odorless, non-reactive, inert gas. In high concentrations, it has an asphyxiating effect. As argon is an atmospheric gas (0.93% vol.), it is generally sourced by separating air. A crude Argon stream containing up to 5% oxygen...

Nitrogen(N2)

History xAbout four-fifths of Earth’s atmosphere is nitrogen, which was isolated and recognized as a specific substance during early investigations of the air. Carl Wilhelm Scheele, a Swedish chemist, showed in 1772 that air is a mixture of two gases, one of which he...
Oxygen(O2)

Oxygen(O2)

Diatomic oxygen gas makes up 20.8% of the Earth’s atmosphere. The constituents of oxides make up about half of the Earth’s crust. The Origin of Oxygen in Earth’s Atmosphere It’s hard to keep oxygen molecules around, despite the fact that...
