Jerry,
We have switched over to a hydrogen generator that is sized at 40% more than our consumption in a full flow, worst case scenario for future expansion. We have had very good performance over the 7 years it has been in service. We keep a cylinder piped in with check valves to carry over the duty if the generator needs service. The purity is an astonishing 6 "nines". I consider it a very good investment and time saver. You will need a DI water loop to feed it.

Hello Everyone,
Here at NIST we are having problems with reliable and timely deliveries of hydrogen. I would like to ask the group what hydrogen purity are you using for your oxidation furnaces and what lead times are you currently seeing?
Thanks!
