[labnetwork] Does anyone use forming gas in vacuum systems

[Bruce Tolleson]

Dear Labnetwork,
  I have a project that requires forming gas (5% hydrogen, 95% Nitrogen) for gettering to reflow metal in a vacuum chamber. Has anyone done forming gas in a vacuum system and what precautions are required for the pumping system?
