Bruker AV-III 700 MHz Spectrometer

The state-of-the-art AV-III 700 spectrometer was installed in 2009 and is jointly owned and operated with the Institute for Marine BioSciences (IMB). This leading edge spectrometer provides researchers with access to a large array of modern experiments and technology. Equipped with both 5 mm and 1.7 mm TCI cryoprobes, 700 MHz NMR data is obtained from this instrument at the current maximum limits in both bulk and mass sensitivity!

Advanced features of the AV-III 700 spectrometer include:

  • a three channel fully broadband console
  • 16.4 Tesla Ultrashield Plus™ magnet
  • Z-axis gradient amplifier and digital lock
  • SampleJET robotic sample changer with sample cooling option
  • 5mm TCI cryoprobe with ATMA
  • 1.7mm TCI cryoprobe with ATMA
  • ultrastable variable temperature control via a BCU-X and BVT-300 controller.

 

Bruker AV 500 MHz Spectrometer

The Avance 500 spectrometer was installed in 2003. This high performance spectrometer operates by default in automation with a BBFO SmartProbe under ICON-NMR software control. Alternatively, researchers can reserve the spectrometer for more sohpisticated experiments, to study reactive samples, to perform variable temperature experiments, or to use the inverse probehead. The spectrometer is controlled by Bruker's TopSpin software (Version 2.1, patchlevel 8).

Features of the AV 500 spectrometer include:

  • a three channel fully broadband console capable of triple resonance experiments
  • 11.74 Tesla Ultrashield Plus™ magnet
  • Z-axis gradient amplifier and digital lock
  • an auto-tune and match (ATMA) broadband observe (BBFO) SmartProbe tunable to all frequencies  between N-14 and P-31 as well as F-19 on the X-coil
  • a triple resonance TXI probe with dedicated H-1, C-13 and N-15 channels, typically used for the study of biological samples
  • a BBO probe with ATMA tunable between N-14 and P-31
  • ultrastable variable temperature control via a BCU-05 and BVT-3200 controller
  • a B-ACS 60™ sample changer to allow unattended analysis of samples in automation

 

Bruker AV 300 MHz Spectrometer

The Avance 300 spectrometer was installed in the Fall of 2010. This is a two channel console with a BBFO-Z broadband double-resonance probe and single axis Z-gradient capability. The narrow bore 7 Tesla magnet is supported on a TMC vibration dampening platform. The spectrometer is controlled by Bruker's TopSpin software (Version 2.1, patchlevel 6).

Features of the AV 300 spectrometer include:

  • a two channel fully broadband console
  • Z-axis gradient amplifier and digital lock
  • BBFO-Z gradient probe with ATMA, tunable to all frequencies  between N-14 and F-19 on the X-coil
  • a SampleXpress Lite™ sample changer with 16 positions to allow unattended analysis of samples in automation
  • ultrastable variable temperature control via a BVT3200 controller.
