Our house nitrogen is being shut off permanently by the end of this month.
We plan to use the boil-off from two 5-foot-tall N2 dewars which we'll plumb
into the old house N2 lines in our lab facility. Has anyone else had
experience with setting up an isolated, stable nitrogen gas delivery system
in your NMR lab/facility?
Also, if you purchase liquid nitrogen to be used as the spectrometer gas
supply in the form of N2 boil-off, how do you recoup the cost of the N2
liquid? Do you charge facility users, and if so, what charge scheme has
worked best?
This is my first posting to this newsgroup, and it's an honor to be a new
member of AMMRL. Many of you may know Bob Addleman here at IU, who has
expanded his interests beyond NMR to become the Systems Engineer in the
Chemistry Department at IU. I've replaced Bob as the NMR Facility
Director.
