NMR spectrometers

The NMR facility consists of several NMR spectrometers hosted in the Chemistry and Physics department and hosts one of the largest NMR suites in New Zealand with five magnets operating between 400 MHz and 600 MHz. The 500 and 600 MHz instruments are used primarily for postgraduate research in chemistry. The other two systems, both operating at 400 MHz, are more commonly used to study physical processes such as rheometry and diffusion. A helium recycling system will shortly be installed as well as an on campus liquid nitrogen production unit for the NMRs.

The NMR facility on level 0 has the following functionality

  • Long Term variable temperature unit -30C for 24 hours
  • Short term VT unit using liquid nitrogen is 6 hours at -100C and 24 hours at 0C.
  • The VT units can be used on any of the NMR systems.
  • All NMRs are equiped with an auto sampler.

3-Channel 500MHz Nuclear Magnetic Resonance Spectrometer

Tuneable X-Nuclei probe indirect detection probe

  • Variable temperature range from -120°C to +150°C
  • Auto tuneable between P31 and N15 including K39 and Ag109. Installed as the standerd probe.

5mm XPH broadband probe for P-X decoupling

  • X is between the N15 and C13 frequency.
  • Temperature range is from -100C to +150C.
  • An 24 position auto sampler.

This probe can be used on special requests if needed. Please enquire at least 2 days in advance.

2-Channel 500MHz Nuclear Magnetic Resonance Spectrometer type JNM-ECZ500S for routine analyses aimed towards 24/7 routine analyses

  • Inverse detection proton sensitive auto tuneable HC probe
  • 64-sample waist-level Auto Sampler.
  • Specifications of installed probe.

NM-03822RO5SS 500 MHZ 5MM FG/RO DIGITAL AUTO TUNE PROBE S. This probe is used for 1H and multinuclear NMR observation while irradiating 1H, or for 1H NMR observation while irradiating one nucleus among multiple nuclei by applying a pulsed magnetic field gradient to a sample using a 5 mm sample tube. Nuclei for observation and irradiation: 1H, 19F, 31P to 15N, 39K, 109Ag Auto Tuning Unit, tuning and matching of each nucleus can be done automatically.

600MHz Nuclear Magnetic Resonance Spectrometer type JNM-ECZ600R

  • 5mm FG/SC Auto Tune to Si29, N15, C13 and P31 SuperCOOLCryogenic Probe and a 5mm FG/RO Digital Auto Tune room temperature indirect detection Probe
  • 64-sample waist-level Auto Sampler.

600MHz Agilent DDR2

  • With a broadband probe located in LB025.
  • Manual operation using VNMRJ.

Two 400MHz Bruker Avance II

  • Magnets are both 89 mm vertical wide-bore cryostats.
  • Located in LB308.
  • Studying the rheology and diffusion of soft materials or the flow dynamics of liquids in porous media.
