Summary
The Varian MR 400 features a standard bore 9.4 Tesla/400 MHz magnet and a OneNMR pulse-field-gradient probe with the capacity for three channels - 2H/1H(19F)/BB. VNMRJ 4.0 is used for data acquisition. This instrument is used for routine 1H/13C characterization experiments, routine X nucleus detection, 1D selective experiments (APT, DEPT, NOESY1D) and basic 2D experiments. Staff will provide training and assistance with initial methods implementation, and will configure the instrument and assist with special projects as required. Extensive methods development may be subject to an hourly staff charge. Instrument features include:
- Autolock, autoshim, and autotuning to nuclei from 15N - 19F.
- This probe uses the 1H channel for 19F experiments.
The MR-400 was acquired in 2010. Information on acknowledging funding and staff assistance for this instrument can be found on this page.
The instrument is located in 1232 Hach Hall. Enquiries should be directed to Dr. Sarah Cady or Dr. Jeff Purslow. Phone 515-294-5975 (Hach office/NMR lab), 515-294-5805 (Sarah office).
