Hydrogen 4.0 from Linde is a high-purity gas (≥ 99.99%) suitable for a wide range of analytical and industrial applications. Its excellent thermophysical properties make it highly effective for combustion, heat transfer, and analytical processes.
Hydrogen is a colorless, odorless, and tasteless gas that burns with an invisible flame. When combined with oxygen, it produces very high flame temperatures. Its clean combustion produces no carbon or soot, ensuring contamination-free processes.
Compared to technical-grade hydrogen (3.0), hydrogen 4.0 offers higher purity, making it suitable for more demanding applications, including gas chromatography and laboratory analyses. It is supplied in pressurized cylinders for safe and convenient use.
