The Bruker Avance III HD 500 was installed in December 2011 (magnet and samplechanger) and July 2013 (console and Prodigy probe).
It is a 2-channel spectrometer with a shielded Ascend magnet.
The magnet sits on a TMC vibration table to protect it from vibrations from the light rail.
There is 1 probe available:
- 5mm Prodigy TCI cryoprobe with z-axis gradients (usually in the magnet)
Only proton (2500:1 S/N), carbon (350:1), and fluorine (2000:1) are available.
This instrument is running under full automation mode with a SampleXpress autosampler.
Limited high temperature is available.
Contact facility staff if non-automated experiments must be run.
The Bruker Avance III 500 was installed in December 2011 (console and probes) and July 2013 (magnet and samplechanger).
It is a 3-channel spectrometer with a shielded Ascend magnet.
There are 2 probes available:
- 5mm BBFO "SmartProbe" with z-axis gradients
Proton S/N: 730:1
Carbon S/N: 250:1
Fluorine S/N: 550:1
Phosphorus S/N: 180:1
- 5mm TBO triple resonance PFG probe (currently in magnet)
Capable of C13 detection with simultaneous H1 and F19 decoupling
Proton S/N: 280:1
Carbon S/N: 220:1
Fluorine S/N: 220:1
Phosphorus S/N: 140:1
Probe changes must be scheduled with the NMR Lab staff.
Variable temperature (+/- 150C) is available.
Instrument is run in manual mode, but automation is available with a SampleCase autosampler.
The Bruker Avance III HD nanobay AM-400 was installed in May 2015. It is a
2-channel spectrometer with a shielded Ascend magnet. A 5 mm BBO SmartProbe with
z-axis gradients is in use.
Proton S/N: 480:1
Carbon S/N: 200:1
Fluorine S/N: 500:1
Phosphorus S/N: 150:1
The probe can be tuned to almost any NMR-active nucleus.
Variable temperature (+/- 150C) is available.
The Bruker Avance III HD nanobay AX-400 was installed in May 2015. It is a
2-channel spectrometer with a shielded Ascend magnet and 60-slot SampleXpress autosampler. A 5 mm BBO SmartProbe with
z-axis gradients is in use.
Proton S/N: 480:1
Carbon S/N: 200:1
Fluorine S/N: 500:1
Phosphorus S/N: 150:1
It is run in full automation mode.
The Bruker Avance Neo was installed in Sept 2020.
Two probes are available:
- iProbe (usu. in magnet)
- room temp BBO probe
This instrument was purchased by and for the undergraduate teaching labs.
