I doubt that this will actually work, but then the Web has brought me some improbable successes before, so it’s worth a shot:
I have a sealed glass cell (Pyrex, I think, if it matters) that I would like to get re-filled with a mix of rare gases– partial pressures of 100mT Ne, 30mT Ar, 30 mT Kr. This will contain an RF plasma discharge to serve as a spectroscopic reference for my experiments, and thus needs to be very clean– I can’t have impurities coming out of the walls and quenching the metastable atoms I’m producing in the discharge.
The company that initially made the cell has not returned email in the last month, and given that it’s actually one guy who’s nearing retirement, may well be out of business. If anybody knows a good source for this sort of gas cell, leave a comment or send me email. As I said, I have an existing cell that can be re-filled, or if that’s impractical, I can buy a new one.
