Nitrogen monooxide Gas

Nitrogen monooxide (NO): Specialty Gas for Advanced Applications

Nitrogen monooxide (NO), a colorless, sparingly soluble gas with high reactivity at ambient conditions, serves dual roles as a critical industrial agent and biological signaling molecule. Though non-flammable, it rapidly oxidizes to nitrogen dioxide (NO₂) and nitrous oxide (N₂O) in air, necessitating strict handling under OSHA PEL guidelines (25 ppm TWA). Supplied in passivated steel cylinders with <0.5 ppm NO₂ impurities, our NO meets SEMI C3.41 and USP-NF standards for precision applications.
