How does the glovebox purifier absorb H₂O and O₂, and regenerate?

The Purifier are composed of two materials: Molecular sieves and a Copper catalyst

1）Molecular Sieves: Water Adsorption and Regeneration - A Physical Adsorption Process

At lower temperatures (T1), the molecular sieve's water saturation capacity (C1) is high, allowing it to absorb significant amounts of moisture.
At higher temperatures (T2), the saturation capacity (C1) decreases, causing the absorbed moisture to be released and evaporated.

Once saturated, the molecular sieve can be regenerated through a combination of heating and vacuum extraction.

2) Copper Catalyst：Oxygen Absorption and Regeneration – A chemical reaction process

Regeneration Process: - A heating and a reduction reaction:
CuO + H₂ → Cu + H₂O
