You seem to be missing the point… and adding a dose of silly pedantry to boot.
The goal here is to clean and completely degas the reactor --- NOT to learn the identity of the last bit of gas which was removed. If they have a top of the line vacuum system, as appears to be the case - and they perform an overnight bake-out procedure which effectively cleans the reactor – then the mass-spec information they would have is redundant. Sure it would be great to do it by-the-letter exactly as Mizuno did it - and in a perfect world we would see that - but not having a record of the last few atoms of gas removed is not going to matter if they get it clean and leak-free. It is absurd to suggest that they should not proceed at all unless they follow every detail precisely. A successful outcome done slightly differently may add more understanding of the process than if done by-the-letter, and if it fails then they know what to do next. From: Jed Rothwell Yeah? When you are a "credentialed professional" does that mean you can ignore the instructions? Do things your way? If it does not work, does that mean we should doubt the original result? It ain't a replication, that's for sure.
