How can I have high Nitrogen content in my tune but low O2 content?
I have an 7890B GC with 5977B and also 7697A Headspace.
We also have a Helium conservation module.
It doesn't make sense. If it's a leak, I must have the same ratio (4:1) For N2 over O2.
Anyone have seen that ?
Is it possible that the helium conservation module valve leak as let Nitrogen mix with Helium ?
