Have you switched to hydrogen carrier gas? What are your experiences?

Hi everyone,

Have you switched to hydrogen from helium as your default carrier gas? What were your experiences? What preparation did you have, and what do you wish you knew?

I'm wondering about helium this week after C&ENews' article on NMR, which discussed helium and the problems associated with its availability.

Securing The Future Of NMR | February 15, 2016 Issue - Vol. 94 Issue 7 | Chemical & Engineering News

Our colleagues in NMR don't have a substitute, but in GC one can switch to hydrogen if helium availability is a problem.

What are your thoughts on...

how long did it take you to set it up and get accurate results
were you able to translate your methods effectively?
did you encounter any institutional safety problems?

Thanks for your insights!

- Josh

Using hydrogen as a carrier gas has been tested on our new Refinery Gas Analyzers and even shows an improvement in sensitivity on the TCD due to the difference of it's thermal conductivity compared to other analytes. See the link to presentation starting with slide 22 Alternative Carrier Gasses for more info. This presentation was given by Roger Firor and JAMES MCCURRY for C&EN
