Bruker

500 MHz AVIIIHD 500 with 60 position SampleXpress sample changer (room 37) and 400 MHz AVIIIHD 400 (room 34):

These spectrometers are both set up to run 1D and 2D experiments using 1H, 19F, 13C, 31P, and 11B experiments. Both have a 5 mm BBFO+ SmartProbe which autotunes to 1H on one channel and X (between 109Ag and 19F) on the other channel and which has single z gradient capability. Software is TopSpin 3.5.

On the Bruker 500, each user may use the instrument for one hour during the day and three hours overnight.  Click here for the Status page for the Bruker 500.

Varian 500 MHz spectrometer.

500 MHz Varian VNMRS (room 34): This three channel spectrometer is primarily used to run directly detected 13C and 1H 1D experiment and 2D inverse detection experiments. With extra training, you can run other nuclei (such as 31P), on it. VT range for the standard probe used on this instrument (the observe, or X-optimized, SW probe): -100 to +120 C. Single z gradient capability. Available probes include: 5 mm SW PFG 1H/19F/X[15N-31P], 5 mm ID PFG 1H/19F/X[15N-31P] and an HCN triple resonance probe. Operated with VNMRJ 4.2 software.

Signup policy for the Varian 500:

  • Signup can be done up to five days in advance.
  • Total spectrometer time in the week for any user is limited to 24 hours.
  • Any individual signup period is limited to 18 hours.
  • If four hours or less are available between 9 AM and 7 PM, and it is less than 90 minutes before the start of the available time, you may sign up, even if you have already used 24 hours.
  • If time between 7 PM and 9 AM is available, and it is less than two hours before the start of the available time, you may sign up, even if you have already used 24 hours.
  • Teaching, instrument maintenance and service will have priority over other spectrometer use.

400 MHz Varian Mercury (room 37): This two channel spectrometer is used mainly for 1H spectra, although it can also detect 31P, albeit with relatively low sensitivity. The inverse detection probe has a VT of -20 C to +50 C. Single z gradient capability. Available probes include: a 5 mm ID PFG 1H/19F/X[15N-31P] and a 5 mm SW 1H/19F/X[15N-31P]. Operated with VNMRJ 4.2 software.
