Product Name:Hydrogen
English Name:Hydrogen
CAS No.:1333-74-0
Aliases:Hydrogen gas
Molecular Formula:H2
Physical Properties:Colorless, odorless, non-toxic, flammable and explosive gas at normal temperature and pressure. Its density is lower than air (1 L of hydrogen weighs 0.0899 g under standard conditions). Insoluble in water, easily diffuses, and has strong reducing properties.
Uses:Used in ammonia synthesis, methanol synthesis, petroleum hydrorefining, float glass protective atmosphere, high-purity gas for electronics industry, and widely used as laboratory carrier gas and clean fuel.
Technical Specifications:
Ultra-pure hydrogen: purity >99.9999%, oxygen (argon) <0.2ppm, nitrogen <0.4ppm, moisture <1.0ppm.
High-pure hydrogen: purity >99.999%, oxygen (argon) <1ppm, nitrogen <5ppm, moisture <3ppm.
Pure hydrogen: purity >99.99%, oxygen (argon) <5ppm, nitrogen <60ppm, moisture <30ppm.
Packaging: 40L GB5099 cylinder, filling pressure 13.5MPa.
Valve outlet: QF-30 or QF-30A valve, W21.8-14 left-hand threaded outlet.
