    HD-500

    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:

    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.








    AV-500

    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:

    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.


    VI-500

    The Varian Inova 500, originally installed in 1989 as a Varian Unity, was upgraded in 1996 with a new console, a third RF channel, PFG (pulsed field gradients), and WFG (wave form generators).

    Several probes are currently available:

    Probe changes must be scheduled with the NMR Lab staff.

    Variable temperature (-20C to +60C) is available,


    AM-400

    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.


    AX-400

    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.


    VI-300

    The Varian Inova 300 was installed in 1996. Four probes are available:

    Variable temperature (-100C to +100C) is available.
    There are no gradients on this instrument.
    The SMS autosampler was installed in March 2014. It can be run in manual mode upon request.
