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...
