Instrumentation

The NMR Facility houses four Varian NMR spectrometers: the Mercury VX 400 (M400), the INOVA 400 (I400), the INOVA 600 (I600), and the Infinity Plus 400 (I+400). The M400 and I400 are used exclusively for liquids NMR experiments, the I600 is used primarily for liquids experiments, but is capable of performing NMR experiments on solids, and the I+400 is used exclusively for solid-state NMR experiments.

The Mercury VX Console, SMS Autosampler, Sample Tray, and Magnet.

Mercury VX 400 (M400) Utilizes an autoswitchable HF/CP probe capable of performing 1D 1H, 19F, 13C and 31P NMR experiments without modifications to the probe. 50 sample SMS autosampler for automated usage. Samples are submitted to the sample queue and run in sequential order. Room-temperature experiments only. Utilizes Red-Hat Linux 5.3 and Varian's VNMRJ 2.2D NMR software package. Ideal for beginners or infrequent users of the NMR facility.

INOVA 400 (I400) Utilizes an autoswitchable HF/CP probe capable of performing 1D and 2D NMR experiments involving 1H, 19F, 13C and 31P without modifications to the probe. Indirect and detect detection of odd-nuclei, such as 11B, 29Si, 77Se. Walk-up instrument. NMR time on the instrument must be booked using the FACES website. Time is limited to a maximum of 2 hours on weekdays from 9:00 am to 6:00 pm. Variable-temperature NMR experiments from -80 °C to +130 °C. Utilizes Red-Hat Linux 5.3 and Varian's VNMRJ 2.2D NMR software package.

The INOVA 400 Console and Magnet

The INOVA 600 Console, Computer and Magnet.

INOVA 600 (I600) Utilizes an indirect detection HCX probe capable of performing 1D and 2D NMR experiments involving 1H, 13C and 31P without modifications to the probe. Indirect and detect detection of odd-nuclei, such as 11B, 29Si, 77Se. Walk-up instrument. NMR time on the instrument must be booked using the FACES website. Time is limited to a maximum of 2 hours on weekdays from 9:00 am to 6:00 pm. Variable-temperature NMR experiments from -20 °C to +80 °C. Low-temperature experiments do not require cryogens for cooling. Capable of performing solid-state NMR experiments with a 3.2mm MAS HXY probe. Utilizes Red-Hat Linux 5.3 and Varian's VNMRJ 2.2D NMR software package.

Infinity Plus 400 (I+400) Wide-bore magnet used exclusively for solid-state NMR experiments. Six Varian/Chemagnetics probes available for use: 3.2mm MAS HX, 4.0mm MAS HXY, 5.0mm MAS HFXY, 7.5mm HXY, 9.5mm HXY, static 5/10mm HX. 3-channel spectrometer with two high-power (kW) broadband amplifiers, plus high-power proton and fluorine amplifiers. Depending on the probe, variable-temperature NMR experiments can be performed from -120 °C to +250 °C. Utilizes Solaris and Chemagnetics' Spinsight 4.2.3 NMR software.
