As I have done geochemical analysis on my samples, I have prepared them in XRF pots roughly 2.5 cm diameter and 2.5 cm high (see picture). The samples are ~1 cm deep.
I am going to "wet" freeze the samples in the same containers I will use for freeze-drying. I want to avoid sample loss which would occur by transferring them to petri-dishes. Is it possible to freeze-dry them in their XRF pots?
If yes, I will be using liquid nitrogen on 4 of the samples before freeze-drying. Can I just pop the pots into the N too?
I don't thnik that the pots are the problem. Normally we use Mylar film for loose samples which is fixed to the bottom by mounting a plastic ring to the pot, and I'm going to guess that both the Mylar film or the ring might break when immersed into liquid nitrogen, or the ring might slip off the pot. Why don't you just give it a try?
@ThomasThank you for your advice, as long as I'm not going to blow the thing up I will do that!
