Nuclear Magnetic Resonance - College of Science and Mathematics

The Nuclear Magnetic Resonance (NMR) Core Facility at 石榴直播 (石榴直播) is part of the College of Science and Mathematics (CSM). It is the only high-resolution NMR facility at 石榴直播; researchers are welcomed from throughout the University. We also provide services to other local universities and external clients.

Before using any of the equipment in 石榴直播鈥檚 NMR facility, you must read and sign the document below. DocuSign is preferred for 石榴直播 faculty and staff.

Equipment

Facility instrumentation: Knowledge of the facility's capabilities will be useful for determining which instruments will suit your needs. Multiple instrument upgrades have happened recently so even experienced users should consult this guide and familiarize yourself with new features.

Bruker 300 MHz AVANCE III HD Instrument (Refurbished Magnet)

This system intended for routine research samples and teaching. Access is scheduled via Faces (see scheduling).

Recent upgrades to capabilities include a new broadband tunable probe for collecting 1H, 19F, 13C, 15N, and 31P in directly detected spectra; two-channel capabilities that enable decoupling and/or double resonance spectroscopy; a new windows PC workstation, automated tuning, and matching; gradient shimming; and access to IconNMR.

Bruker 400 MHz AVANCE III HD Instrument (Ascend Magnet)

This system is intended for routine and advanced research samples. Access is scheduled via Faces (see scheduling).

Capabilities include: 24 tubes SampleCase automated sample insertion, a broadband tunable 2-channel probe capable of collecting 1H, 19F, 13C, 15N, and 31P directly detected spectra; two-channel capabilities enable decoupling and/or double resonance spectroscopy e.g. HSQC between 1H and a broadband nucleus; temperature stabilization via BCU or liquid nitrogen for variable temperature NMR; automated tuning and matching; gradient shimming; and access to IconNMR.

Bruker 600 MHz AVANCE III HD Instrument (Ascend Magnet)

This system is intended for advanced research samples, for final publication-quality data collection, polymers, and biomolecules. Access is scheduled via Faces (see scheduling) and may require assistance from Dr. Leeper.

This new high-field system provides the following capabilities: SampleJet automation (5 x 96 samples or 30 conventional tubes); triple resonance 1H, 13C, 15N cryoprobe with very high sensitivity; three channels for simultaneous decoupling of 15N and 13C or triple resonance spectroscopy; automated tune/match; gradient shimming; temperature stabilization via BCU; Linux workstation, non-uniform sampling for reduced experiment time in multidimensional experiments, and access to IconNMR.

Fees and Scheduling

Please email the listed facility coordinator below to inquire about the current usage rates.

Scheduling:

NMR time can be booked below with Group 石榴直播_CHEM. Users must obtain a Faces login and password from Dr. Leeper if they have never done so before. Unscheduled use of the 300 is no longer permitted. It is strongly recommended that users for the 300 and 400 limit blocks to one hour and those who wish to book longer blocks should do so for nights and weekends. After each experiment is completed users must sign the logbook using a regular ballpoint pen (not a sharpie or pencil) to confirm that the spectrometer remains in working order and is ready for the next user; each spectrometer has its own paper logbook.
