Available Equipment

The Solid-State NMR Facility comprises…

 

Bruker Avance III HFXY spectrometer with 9.4 T wide-bore magnet (400 MHz for 1H) and the following probes:

  • 7 mm HX – large volume, slow MAS suitable for insensitive nuclei where fast MAS is not required (and also for odd-shaped samples such as extruded polymer rods that cannot easily be ground into a powder). X range from 15N to 31P.
  • 4 mm HX – “workhorse” probe capable of most routine experiments. X range from 15N to 31P.
  • 4 mm HFXY – with a range of inserts suitable for multinuclear correlation and/or decoupling experiments.
  • 4 mm “low-γ” HX – suitable for nuclei with very low Larmor frequencies. X range from 109Ag to 23Na.
  • 1.9 mm HFX – rapid MAS (up to ~40 kHz) suitable for high-resolution 1H and 19F spectra and paramagnetic materials. X range from 17O to 117Sn.

 

Bruker Avance III HXY spectrometer with 14.1 T wide-bore magnet (600 MHz for 1H) and the following probes:

  • static 5 mm HX – suitable for studying static lineshapes, often as a function of temperature (e.g., to probe motion within the sample). X range from 15N to 31P.
  • 2 × 4 mm HX – “workhorse” probes capable of most routine experiments. X range from 15N to 31P.
  • 4 mm HXY – with a range of inserts suitable for multinuclear correlation and/or decoupling experiments.
  • 4 mm “low-γ” HX – suitable for nuclei with very low Larmor frequencies. X range from 109Ag to 23Na.
  • 3.2 mm HX – “workhorse” probe capable of most routine experiments. X range from 15N to 31P.
  • 1.9 mm HX – rapid MAS (up to ~40 kHz) suitable for high-resolution 1H spectra and paramagnetic materials. X range from 15N to 31P.
  • 1.9 mm HXY – with a range of inserts suitable for multinuclear correlation and/or decoupling experiments on samples that need rapid MAS.
  • 1.3 mm HX – very rapid MAS (up to ~60 kHz) suitable for high-resolution 1H spectra and paramagnetic materials. X range from 15N to 31P.

 

Other equipment of note:

  • Both spectrometers are equipped with chillers/heaters for operating routinely in the range –10 to +80 °C. Additional high-temperature caps (4 mm rotors only) and liquid nitrogen chilling (static experiments only) can extend the range from –100 to +120 °C.
  • 4 mm Si3N4 rotors allow the acquisition of spectra that would suffer from a background with the standard YSZ rotors (mainly 89Y and 17O)
  • 4 mm “fast MAS” rotors capable of handling large sample volumes at MAS rates up to 18 kHz.
  • 4 mm HRMAS inserts capable of containing semi-liquid samples (gels, sediments, etc.) and achieving MAS rates of up to ~8 kHz.
