Air Liquide offers gases for all industrial needs.


Air Liquide manufactures nitrogen dioxide as pure gas with purity up to 99% or as part of a specialty gas mixture that includes air or nitrogen. Nitrogen dioxide is used in many applications, primarily in environmental monitoring. Additionally, nitrogen dioxide in balances of air nitrogen at various concentrations are used as span gas calibration mixtures for engine emissions testing in the automotive industry and are Part 86 compliant.

When a smaller quantity of gas is warranted, Air Liquide delivers nitrogen dioxide mixtures in non-returnable Mini-Mix cylinders, designed specifically for industrial hygiene and safety and laboratory applications.
