YIGAS Gas Supply

Nitrogen is a colorless, odorless and non-toxic gas at room temperature and pressure. It does not burn or help to ignite. It is separated from air by distillation or pressure swing adsorption. When the amount of nitrogen in the air increases, it will dilute oxygen and cause asphyxiation. Liquid nitrogen can cause frostbite when it touches the skin. Nitrogen is used in food preservation and packaging, welding and metal processing, healthcare, agriculture, and electronics manufacturing.

Hydrogen

Hydrogen is the lightest and most abundant element in the universe. It is a colorless, odorless, flammable gas with extremely high combustibility and very low solubility in water. The density of hydrogen is 0.089 g/L (101.325 kPa, 0°C), which is only one-fourteenth that of air, making it the lightest known gas. As a versatile zero-carbon energy carrier, it can drive decarbonization efforts in sectors such as transportation, manufacturing, and energy. Hydrogen has a wide range of applications in various fields such as industry, energy, food manufacturing, medicine, and aerospace.

Oxygen

Oxygen (O₂), a colorless, odorless gas constituting 21% of Earth's atmosphere, is vital for aerobic life and industrial innovation. While non-flammable, it vigorously supports combustion, enabling high-efficiency energy release. Oxygen plays a vital role in numerous industrial applications, including steelmaking, chemical and pharmaceutical manufacturing, as well as brazing, welding and cutting of steel and other metals. It is also used in rocket propellants, oxygen therapy and life support systems. Our oxygen is available in gaseous and cryogenic liquid forms (distinctive pale blue when liquefied) with purity that meets industrial and medical grade standards (≥99.5% industrial grade, ≥99.995% medical grade).

Acetylene

Acetylene, a colorless, highly flammable hydrocarbon (C₂H₂), is the simplest alkyne with a distinctive triple carbon-carbon bond. This unique structure grants it unparalleled reactivity, making it a cornerstone in industrial and chemical processes. Acetylene is a widely used fuel gas, used for welding, brazing, cutting, and spot heating of metal surfaces. It is also used in the production of polyethylene plastics, rubber, dyes and pigments, pharmaceuticals, and pesticides. Supplied in acetone-dissolved cylinders for safe storage, our acetylene meets ISO 14175 standards with ≥99.6% purity and sulfur/phosphorus impurities<0.1 ppm.

Ammonia

Ammonia is a colorless gas with a characteristic pungent odor, widely recognized as a cornerstone of modern agriculture and industry. As a highly soluble compound with alkaline properties, it enables critical nitrogen transfer processes. Ammonia is used in the production of agricultural fertilizers, industrial refrigeration, cleaning products, semiconductor and electronics manufacturing, and fuels. Supplied in pressurized cylinders, bulk liquid tanks, or custom on-site solutions to meet diverse industrial demands.

Tetrafluoromethane

Tetrafluoromethane (CF₄), a colorless, non-flammable gas with exceptional thermal stability, serves as a critical halocarbon in precision industries. With a boiling point of -128°C and low global warming potential (GWP 7,390), it combines chemical inertness with high plasma selectivity, making it ideal for mission-critical processes. Tetrafluoromethane is used in electrical insulation, aluminum production, semiconductor etching, trace gas detection, and cosmic ray detection. Our CF₄ is supplied in ISO-certified cylinders at ≥99.999% purity (Grade 5.0).

Nitrogen Trifluoride

Nitrogen trifluoride (NF₃) is a stable, non-flammable specialty gas engineered for high-performance plasma processes in critical electronics production. NF₃ is used as a chamber cleaning gas in the manufacture of semiconductors, flat panel displays and other electronic devices. As a low-residue fluorine source, it enables ultra-clean manufacturing with reduced environmental impact compared to legacy gases.

Carbon Monoxide

Carbon monoxide is a colorless, odorless, and tasteless gas at room temperature and pressure. It is extremely poisonous to humans and animals, binding irreversibly to hemoglobin and causing oxygen deprivation. Exposure to concentrations above 35 ppm can lead to headaches and dizziness, while levels exceeding 800 ppm are rapidly fatal. It is generated through incomplete burning of materials like coal, gasoline, natural gas, and wood. Despite its toxicity and potential harm to human health, carbon monoxide is also a valuable compound used in chemical manufacturing and synthesis, environmental monitoring, metallurgy, medical research, advanced industrial processes, food preservation, and advanced technological processes.

Ethane

Ethane is an important chemical raw material. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. Ethane is a colorless, odorless gas at room temperature and pressure. It's extremely flammable and can form explosive mixtures with air. Ethane is primarily used to produce ethylene, which is then used to manufacture plastics, antifreeze, and solvents. In addition, it is used in power generation and cryogenic cooling.
