High-Purity Gas

Carbon Dioxide in Argon

Mixture gas of CO2/Ar is a compressed gas, does not support combustion, cylinder containers are easy to overpressure when heated, and there is danger of explosion. It is used as a welding gas.

Helium Purchasing Guide: Multiple Channels for You to Choose

Helium (6N)

Helium is inert and the least soluble of all gases in liquids and is therefore used as a pressurization. Being inert, helium is used as a constituent in neutral atmospheres e.g., in heat treatment applications requiring a protective atmosphere.

Helium is used extensively in the welding industry as an inert shielding gas for arc welding. It is also used in conjunction with helium (“leak”) detectors to test the integrity of fabricated components and systems.

Nitrogen Trifluoride (5N)

The chemical formula of nitrogen trifluoride is NF₃. It is a colorless, odorless and stable gas at normal temperature. It is a strong oxidant. High purity nitrogen trifluoride has excellent etch rate and selectivity, and it is also a very good cleaning agent. Jinhong can provide you with high-purity nitrogen trifluoride gas to improve your semiconductor process.

Silane (6N)

Silanes are compounds of silicon and hydrogen, including monosilane (SiH4), disilane (Si2H6), and some higher-order silicon-hydrogen compounds. Among them, monosilane is the most common, and monosilane is sometimes abbreviated as silane. Silane is a colorless, air-reactive and suffocating gas.

Xenon (6N)

The chemical formula of xenon is kr, which is a natural noble gas with the largest relative atomic mass and the highest density. The main application of xenon is in the lighting industry, but also used in the medical and semiconductor industries.
