The 401 deoxygenation column is a specialized packed chromatography column used in gas chromatography (GC) analysis to remove trace amounts of oxygen from gas samples and achieve separation of oxygen, argon, nitrogen and other components. It was developed and produced by Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. and is widely used for the determination of trace amounts of oxygen and argon in industrial hydrogen, high-purity gases and other samples.
Core parameters and characteristics
Model: 401
Specification: commonly 3m x 3mm (inner diameter) or 3m x 1/8 inch, with a filler particle size of 0.4-0.8mm (60-80 mesh)
Maximum operating temperature: 280 ° C
Material: Stainless steel tube or glass tube (optional)
Deoxygenation ability:
The residual oxygen content can be as low as~10 ⁻⁵ mL/L (about 10 ppb)
Deoxygenation capacity up to 15 mg/g deoxidizer
After oxygen inhalation, the color changes from green to dark brown, indicating visual failure
Regeneration: After failure, it can be activated and regenerated by high-temperature hydrogen gas, and reused
Main application areas
Purity analysis of industrial hydrogen: According to GB/T 3634.1-2006 "Hydrogen Part 1: Industrial Hydrogen", separate and determine impurities such as O ₂, Ar, N ₂, etc
