HNG type high-efficiency gas purification stainless steel deoxygenation tube
This product is made of stainless steel, offering pressure resistance and high-temperature resistance. It is used to remove trace oxygen from nitrogen, argon, carbon dioxide, and other inert gases. The deoxygenation tube features room-temperature deoxygenation, deep purification, large oxygen capacity, and is equipped with various fitting sizes, including 3mm, 6mm, 6.35mm, and Swagelok quick-connect fittings. After the deoxygenation tube becomes saturated with oxygen, it can be regenerated by the user and reused repeatedly over a long service life.

Instructions for Use：
Connect the gas line that has already been purged with gas to one end of the deoxygenation tube, then connect the other end fitting, and the tube is ready for use.
※ Note:
Deoxidizer that has been activated or regenerated must not be exposed to air or come into contact with large amounts of oxygen; otherwise, the service life of the deoxidizer will be affected.
Regeneration Method：
After the deoxidizer becomes saturated with oxygen, regeneration is required. Introduce pure nitrogen or other inert gas at a flow rate of 100–200 ml/min while heating the deoxygenation tube, evenly raising the temperature to 180 - 250℃.
Introduce hydrogen into the nitrogen stream at a flow rate of 100–200 ml/min. Due to the temperature rise and the introduction of hydrogen, water vapor will be discharged from the gas outlet. The regeneration reaction proceeds layer by layer along the direction of gas flow. When the regeneration front moves from one end to the other, and no water vapor is detected in the vented exhaust gas, regeneration is essentially complete. Turn off the nitrogen while keeping the hydrogen flowing, and continue gas flow for 1 hour. Then turn off the hydrogen and the electric heater, and introduce a trace amount of nitrogen. Once the temperature drops to room temperature, close the gas supply. The activation is complete, and the tube should be sealed and kept on standby.
