Oh yeah duh. I used to hit my knee on the mini-tank of helium next to the gc all the time at one place I worked. …now they can come with hydrogen generators
This question is out of my current wheel-house and so I don’t feel comfortable commenting until I can think and read more. Just need to find some time.
Thanks for including me. I’ll get back
I’m currently convinced that @Greenleafpro wasn’t quite with us. I can see no reason for a major functional difference between N2, He, or Ar in this application at 50-60 PSI.
if we were feeding liquid, it would be a different game, but I still think He would be more problematic rather than less problematic than Ar.
As a molecular geneticist I’m also well outside my formal training
