The Varian MR-400 features a narrow bore 9.4 tesla/400 MHz magnet equipped with a OneNMR pulse-field-gradient probe. VNMRJ 3.0 is used for data acquisition, and the MNova software is typically used for data processing. This instrument is used for routine 1H/13C characterization experiments, routine X nucleus detection, 1D selective experiments (APT, DEPT, NOESY1D) and 2D experiments.
- The OneNMR probe features autolock and autoshim, and is capable of auto tuning to nuclei from 15N - 19F. This probe uses the 1H channel for 19F experiments.
- Variable temperature capabilities for experiments in the range of -80 to +130 °C.
The MR-400 was acquired in 2010, NSF CHE 0946687*
This instrument is intended to be used by students and other researchers. Staff will provide training and some initial methods development assistance, and will configure the instrument and assist with special projects as required. The hourly rates are listed below. NOTE: There is a minimum billable increment of twelve minutes.
