Dear friends,
We have a serious debate at our department regarding the use of air
or nitrogen for MAS and VT controls. Due to a reduction in our
budget, we are trying to cut down the operation costs in all
possible way. There is a huge difference in cost for using “Nitrogen
gas” (either from boil off or from N2 generator) compared to using
“clean dry air”.
As far as I spoke to different NMR persons, everybody told me it is
not a problem to use air for MAS and for VT for room temp expts. But
I have a hard time convincing one new faculty who somewhere got the
idea that air is harmful to NMR probes and HAVE to use Nitrogen gas.
I finally decided to ask the AMMRL people, who are the NMR experts, to
help me make a decision whether to use “clean dry air” or nitrogen gas.
Thanks
Damodaran
