The NMR Facility is open for Phase 3. Read the guidelines below.

Please follow all new guidelines outlined in the COVID 19 – Phase 3 operations document.  Users should also review the Chemistry Department’s Guidelines for working in the building.  Additional information about COVID-19 compiled by the department can be found here.

NMR Facility hours match the Chemistry Building hours:  users should not enter the building or Facility outside of these hours.

A quad nucleus probe (QNP) is now installed on Eos (400), and Eos is open for use.  The QNP probe will be the replacement for the spectrometer until the normal BBFO+ probe returns from Bruker.  The QNP probe shims well, and can detect 1H, 13C, 19F and 31P.  It cannot detect other nuclei.  It works well with IconNMR.  It is VT capable (in topspin only) from -120 to +100C.

The new 500 MHz spectrometer, Nyx, is now available to users that have appropriate training.  New capabilities for operando operation are not yet installed, but the spectrometer has a BBFO+ probe installed that can detect any NMR-active nucleus.  It will operate over a VT range of -120 to +120C.  The functionality is very similar, albeit with better sensitivity, to what persephone had when it was in liquids mode.  It you want to start using Nyx, you must have taken Chem 636 or had equivalent training.  Email nmrstaff@chem.wisc.edu to schedule a time when we can get you introduced to the spectrometer.  That session will take about 10 min, assuming you’ve previously used Eos (in topspin mode), Persephone, and/or the 600.

Phoebe (600) is available to all users that were using it prior to the pandemic shutdown, or trained since we re-opened.  Users must email nmrstaff@chem.wisc.edu to have us meet you during your first session on the spectrometer since the hard disk failure about a month ago.

The full MR Facility has resumed “normal” accounting practices for applying charges.  All users must be aware that fees are not based on calendar requests, nor are they based on IconNMR use.  Under calendared use, charges are based on the time logged into the spectrometer (independent of whether an experiment is running or not).  That has worked well in the past, and is an accurate and efficient method for doing the accounting.  It is the user’s responsibility to sign-up and use just the time needed under calendared use.  Log out when done.  If the user assumes someone else will logout for them and that does not happen, the full amount of time the user is logged in will be charged.  Do not signup for a set of short experiments unless someone will stick around to log out when the experiments are done.
