Selecting hydrogen compatible vacuum pump
Hello!
I'm running an experiment that requires me to purge a small chamber of oxygen before filling it with some hydrogen gas and heating it up. Once my experiment is complete, I need to safely exhaust the heated hydrogen (~200C). I am looking for a vacuum pump for this purpose. I have a dry scroll pump on hand but from what I have read, this is not explicitly hydrogen compatible. However, I know of other labs at my university which work with hydrogen and use a regular dry scroll pump.
I'm looking for advice from people that have worked with hydrogen in the past. Do I need a specific hydrogen compatible vacuum for my experiment or does a dry scroll pump fit the bill? If not, I would appreciate any recommendations for vacuum pumps that would work well for my purpose.
Thanks for the advice!
