| 300 MHz Spectometer: |
| 7.05 Tesla (300 MHz for protons) magnet with 20 gradient shim system. Two channel console with: waveform memory and amplitude shaping, two 50-100W transmitters, single axis pulsed field gradients, digital variable temperature controller, and UNIX workstation with XWIN-NMR data acquisition and processing software. |
| Probes: |
| 5 mm inverse broadband (1H and 109Ag to 31P) single axis gradient probe (the default probe) |
| 5 mm quad 1H 13C 31P 19F single axis gradient probe |
| 10 mm multinuclear probe - 109Ag to 31P with 1H decoupling |
| Primary Uses: |
| The inverse broadband probe of the DRX-300 provides the ability to measure 1H and any other nucleus in the range of 109Ag to 31P. The quad probe provides the ability to measure 1H and 19F/13C/ 31P all with the same 5mm probe switched under computer control. The broadband and quad probes can be readily interchanged and their primary role is in the characterization of small molecules, both synthetic and natural. Routine analysis of these compounds benefits from the automation software and computer controlled switching between nuclei on the 5mm probe. Gradient-based solvent suppression is available. In addition to small molecule studies, this instrument is used to check samples prior to long experiments on the 600, and also provides an additional field strength for relaxation measurements. Some 2D pulse sequence development may be done on the DRX-300, which is hardware and software compatible with the DRX-600. |
