Judgment Method of Glove Box Purification Materials

Etelux inert gas glove box relies on inert gas circulation to bring H2O and O2 to the purification system for filtration. H2O and O2 will be adsorbed on the purification material at the purification system. Only inert gas can be returned to the chamber, so that after a period of time, the O2 content of the H2O in the tank will be less than 1ppm.

In the process of using the purification system, the purification material will continuously absorb H2O and O2, and the purification material will be saturated after the service life expires, so it needs to be regenerated.

Different purification materials are also divided into good and bad, how should we judge?

1. First of all, it is premised that the equipment is not leaking, the pipeline and the like are tested with vacuum pressure, and the H2O, O2 probe is normal.
2. The service life of the equipment (about five years)
3. Equipment use environment (more organic solvents, electrolytes and other volatile solutions)
4. Failure to replace activated carbon in time
5. H2O and O2 cannot be maintained after regeneration. It will rise in a short time.
6. Open the purification material and check the appearance. The surface has discoloration and redness, cracks on the surface, and fragility.

Comprehensive 6-point judgment can determine the problem of purification materials, it is recommended to replace the purification materials

After replacing the purification materials, you need to pay attention to:

1. Change the activated carbon regularly
2. After finishing the experiment with organic solvent and electrolyte, you can clean the equipment for more than 20 minutes.
