Nitric Oxide (NO)
Product Overview
Nitric oxide (NO)is a versatile specialty gas serving both semiConductor manufacturing and medical applications. In the electronics industry, it is used as a dopant source, oxidation agent, and calibration gas for emissions monitoring. In healthcare, NO is a therapeutic gas for pulmonary hypertension, requiring the highest purity standards .
According to TECHCET data, the global electronic specialty gas market reached $4.64 billion in 2025, with reactive gases like NO requiring specialized cylinder handling and passivation treatments. The Asia-Pacific region accounts for approximately 74.4% of global semiconductor gas consumption .
