EQUIPMENT AT THE NUCLEAR MAGNETIC RESONANCE CENTER


Varian NMRS 500 (5 ch)

  • This is a Research grade 5 channel instrument equipped for double and triple resonance experiments in both solids and liquids. It includes a suite of probes to do essentially every useful permutation of triple resonance experiments, including 1H/13C/X (where X covers essentially the entire range of nuclear resonance frequencies). The instrument was purchased to perform diffusion experiments with high gradient strengths (120 Gauss/cm), and very high temperature (up to 250 deg. C) solution and solids experiments.
  • Instrument rates for UA users can be found on the Magnet Intranet Rates page. NMRS 500-02 GDYR 103a
  • The nature and variety of experiments which are performed on this instrument require that time be scheduled at least one (1) to two (2) weeks in advance. Contact lab personnel by Noon on Wednesdays to request instrument time for the following 2 weeks.

Varian NMRS 500

  • This is a Research grade 2 channel instrument for H/X double resonance experiments. It is equipped with a robotic sample changer, auto-tune and auto-shim capabilities for continuous unattended instrument optimization and operation. This instruments configuration will alternate between robotic operation of 10- and 5-mm dual broadband probes (based on demand).
  • For access to this instrument, please contact Dr. Dudipala for training and checkout. Once you have been checked out to operate this instrument, time can be reserved via the Intranet Scheduling page.

Varian MERCURY 300

  • This NMR instrument is a 300 MHz spectrometers equipped to observe 1H/19F and 13C/31P. In addition to routine 1-D 1H and 13C spectra, homo- and heteronuclear decoupling, APT, DEPT, COSY, HETCOR (Heteronuclear shift correlation), homonuclear-2DJ, NOE Difference and saturation experiments etc., can be performed.
  • This is intended to be walk up instruments for undergraduate and graduate student research. Only people who have been checked out by lab personnel are allowed to use the instrument.
  • These instruments are intended for routine walk-up access, however up to 30 minute time slots may be reserved between the hours of 8:00 AM and 5:00 PM.; two hour time slots can be reserved from 5:00 P.M. to 10:00 P.M., and up to 10 hours can be reserved between 10:00 P.M. and 8:00 AM.; Signup is via a reservation system accessible via the Magnet Intranet page.

EQUIPMENT AT THE MOLECULAR CHARACTERIZATION LABORATORY


GPC - Room Temperature Instrument

Typically running with THF mobile phase with two choices of detector arrangements:

  • A. Viscotek Triple Detector operation, TriSEC
    • Waters Differential Refractometer, Model 410
    • Viscotek Viscometer, Model 100
    • Wyatt Dawn EOS light scattering@90º angle
    • The PC based data system uses a Viscotek 3-detector interface and TriSEC software. Data analysis can also accommodate both universal calibration (2 detectors) and conventional calibration (1 detector) but these require that current column calibration data be on file.
  • B. Wyatt Multi-Angle Laser Light Scattering, MALLS
    • Waters Differential Refractometer, Model 410
    • Wyatt Dawn EOS light scattering employing 15 angles
    • The PC based data system uses Wyatt ASTRA software.
  • Note: both Viscotek and Wyatt claim absolute results for their respective approaches to molecular weight measurement.
