Nitric Oxide (NO): High-Purity Reactive Gas for Semiconductor Critical Processes and Medical Applications
Nitric Oxide (NO), a type of Specialty Gas, is a colorless, toxic, and strongly oxidizing gas (molecular weight: 30.01) with paramagnetic properties. It rapidly reacts with oxygen at room temperature to form nitrogen dioxide (NO₂). Its density at 20°C is 1.27 g/L, slightly higher than air. As a critical reactive gas, nitric oxide plays an irreplaceable role in semiconductor thin-film deposition and medical gas therapy.
YIGAS is a nitric oxide gas supplier providing 99.9% high-purity NO for electronics manufacturing, specialty gas blending, analytical testing, chemical processing and research applications. Our standard nitric oxide is supplied in a 47L gas cylinder with a DISS 728 valve connection. Each cylinder contains approximately 1,700 liters of NO at a filling pressure of approximately 36 bar. Nitric oxide is a reactive specialty gas. When selecting a supplier, buyers should consider not only the total purity but also the limits for nitrogen dioxide, nitrous oxide, carbon dioxide and nitrogen. Cylinder preparation, valve compatibility, batch testing and transportation capability are also important for maintaining stable product quality.

Nitric oxide can also be used as a controlled reactant or research gas in chemical and laboratory processes.
Typical applications include:
Chemical reaction studies
Catalyst research
Surface treatment research
Gas sensor development
Spectroscopy
Materials research
Laboratory gas blending
Nitrogen oxide chemistry
Process development
Equipment testing
The appropriate purity depends on the sensitivity of the experiment and the effect of impurities on the process.
For general chemical research, the standard 99.9% grade may be sufficient. More sensitive analytical or electronic applications may require lower impurity limits.
Nitric oxide is toxic and reactive. It must only be handled by trained personnel using suitable gas equipment.
General precautions include:
Store cylinders in a secure and ventilated area.
Keep cylinders away from heat and incompatible materials.
Secure cylinders in an upright position.
Use equipment designed for toxic and oxidizing gases.
Confirm that the regulator is compatible with DISS 728.
Prevent air and moisture from entering the cylinder.
Leak-test connections before use.
Use appropriate gas detection and ventilation.
Keep valve protection devices installed during storage and transport.
Follow the current Safety Data Sheet.
Prepare emergency procedures for leaks or exposure.
Follow local occupational safety and dangerous-goods regulations.
NO reacts rapidly with oxygen to form NO₂. Gas delivery systems should therefore be designed to limit air ingress

Ethylene, a colorless, slightly sweet-smelling hydrocarbon (C₂H₄), is the backbone of modern petrochemical industries. As the simplest alkene with a reactive carbon-carbon double bond, it exhibits high flammability (explosive range: 2.7–36% in air) and serves as a critical building block for synthetic chemistry. Used as feedstock for LLDPE/HDPE, epoxy ethane and ethanol production. Compatible with swing-reactor and high-pressure tubular processes. Our ethylene is supplied in high-purity grades (≥99.9% polymer-grade, ≥99.5% chemical-grade) via ISO-certified cylinders, backed by a reliable gases supply network to ensure consistent delivery to your operations.
Propane, a colorless, odorless, and highly flammable alkane (C₃H₈), is a cornerstone of liquefied petroleum gas (LPG) with a boiling point of -42°C, enabling efficient storage and transport as a liquid under moderate pressure. Propane is renowned for its high calorific value (50.33 MJ/kg) and clean combustion properties, making it an ideal choice for high-temperature brazing, metal cutting, forklift fuel, and LPG blending. Supplied in ISO-certified cylinders or bulk tanks through our dependable gases supply network.
Sulfur dioxide (SO₂), a colorless gas with a pungent odor and high water solubility, is a versatile inorganic compound widely used in chemical manufacturing, pulp and paper processing, and as a food desiccant and preservative. It is also commonly used in sulfuric acid production and in the desulfurization of natural gas and oil. With a boiling point of -10°C, it serves as both a reactive intermediate and a functional additive, though its environmental impact as a primary air pollutant requires stringent handling. Our SO₂ is supplied in ISO-certified cylinders.
Ethylene oxide (C₂H₄O), a colorless, flammable gas with a faintly sweet odor, is a highly reactive epoxide critical to modern industrial and medical applications. It is primarily used for the cryogenic sterilization of disposable syringes, endoscopes, and pacemakers. With a boiling point of 10.4°C, it transitions to a liquid below this temperature, exhibiting excellent miscibility with water, ethanol, and ether. Its explosive range (3–100% in air) and carcinogenicity (Class 1B per IARC) necessitate stringent handling under NFPA 704 protocols (Health 4, Flammability 3). Supplied in ISO-certified cylinders or nitrogen-diluted blends.
Methane (CH₄), a type of Industrial Gas, is a colorless, odorless, and non-toxic organic compound with distinct physical characteristics. Under standard temperature and pressure (STP), methane exists as a gas with a density approximately 0.55 times that of air, making it lighter and minimally soluble in water. It transitions to liquid at -161.5°C (boiling point) and solidifies at -182.5°C (melting point), remaining gaseous under ambient conditions. Methane is commonly used as a fuel for heating, cooking, and power generation. Because it is an odorless hydrocarbon gas, it is often mixed with substances that have an odor to report leaks or spills in pipes and systems.
