Safe purge gases for Linkam stages
Linkam stages have been tested with Argon (Ar) and Nitrogen (N2) as purge gases.
Do not use Helium (He) or Hydrogen (H2) gas in a Linkam stage. The reason for this is the extremely high thermal conductivity of these gases which will put a much greater than normal thermal load on the heater, causing the heating performance to be poor and, in extreme cases, causing the heater to burn out.
Other gases may be used at your own risk, but we do not recommend using corrosive gases as these are likely to damage the internal components of your stage.
Before using any gas in your Linkam stage, you should refer to the appropriate Material Safety Data Sheet for the substance.
