EPMA of liquid metals

[Probeman]

Has anyone here ever tried to probe liquid metals such as Ga-In eutectic?

We have a customer looking at various liquid metal to metal reactions and if I look up the vapor pressures it doesn't look problematic:

But I don't know what will happen when the liquid metal is hit by an electron beam...  has anyone tried EPMA on Ga-In eutectic liquid metals?

Edit by John: I found the paper attached below which gives ~10-9 mm Hg at 200 C or ~10-7 Pa.
