Generally the glove box system need a solvent adsorber (charcoal), in your case possibly the solvent trap. It is important for the glove box generator. If you have less amount of solvents inside, the life time of generator is longer, that means the time you have before you need to regenerated the glove box system. If you have large amount of solvent, the life time of your generator is reducing. I hope, I could answer your questions.

Glove box can content dry air atmosphere, dry inert gas atmosphere etc. In case of glpve box with dry inert atmocphere it can be installed a system for catching oxygene traces based on activated copper into silicagel sorbents. This system can also remove and solvent traces.

In case of dry air glove box solvents trap can be constructed like a tray with activated carbon. Also iy can be a tray with P2O5 (phosporous anhydride), it can catch a moisture and solvent's vapours together.
