- 9.4 tesla/400MHz, narrow bore
- Pulse field gradient probe, capable of tuning to nuclei from 15N - 19F
- Uses the 1H channel for 19F experiments.
- Used for routine 1H/13C characterization experiments, routine X nucleus detection, 1D selective experiments (APT, DEPT, NOESY1D) and 2D experiments.
This narrow bore 9.4 tesla instrument is equipped pulse-field-gradients (PFG), four channels, shaped pulse, digital filtering. Two 5 mm PFG probes, one triple resonance inverse with 2H/31P/1H/BB channels and the other normal geometry with 2H/1H/BB channels, are capable of handling the full range of nuclei, including fluorine. The normal probe is used extensively for variable temperature experiments and has a temperature range of -150 °C to +150 °C. This instrument is principally used for routine walk-up, kinetics and multi-dimensional experiments. The inverse probe has a temperature range of -50 °C to + 50 °C.
The DRX-400 was acquired in 1995.
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.
