Hello All,

In order to make some calcium test devices, we will be needing to expose calcium pads (100 nm of thickness) to nitrogen atmosphere. We do not expect the exposure time to be more than a few minutes. Twenty minutes could be considered a safe upper limit.

I am wondering if anyone who has had a similar experience can tell me if this would lead to severe degradation of the calcium pads.

The oxygen content inside the glovebox is assumed to be less than 1000 ppm. I have reaction rate data for oxygen, and I can take care of that. I'm mostly concerned with reaction with nitrogen itself, for which I have not been able to find any reaction rate data.
