Pure, ultra pure or in mixtures for your specific needs

Nitrogen is mainly found in the atmosphere, where it accounts for 78% by volume of the air we breath. But nitrogen is also found:

  • in the Earth's crust, to a limited extent (in the form of nitrates, etc.),
  • in organic form (in the living or dead plants and organisms which form humus)
  • and in mineral form (ammonia), and thus contributes to soil fertility.

In gaseous or liquid form, nitrogen is an inert, colorless, tasteless, odorless, chemically inert and non-flammable gas.
