Hi all,
We're in the process of budgeting for a new NMR to replace our slowly
failing old one, and I've recently started to read about this impending
LHe supply cost increase in 2015. Having read through a few primers about
helium recovery, I'd like to ask the list about their experiences with
helium recovery.
Also, Bruker apparently has a new series of Aeon magnets that have no LN
and use LHe with active refrigeration with LHe fill times every 18 months
instead of 6 months. Does anyone have any experience with these (fairly
new) magnets? Would the infrastructure, service costs, and schedule
compare to the helium refrigeration system for a cryoprobe?
I've read that setups for helium recovery/reliquefaction on-site are in
the $300-500k range, but how does this compare against an actively
refrigerated magnet and whether it is worth justifying the initial costs?
I'm curious as to the opinions of the others on the list.
Thanks & Regards,
Norman Chu
