Analytical NMR Service & Research Center

Advanced NMR Instrumentation

Feel free to contact us to select the appropirate spectrometers to meet your needs.

For routine NMR screening : A walk-up 400 MHz fully automated spectrometer is available for H-1, C-13, P-31 and F-19 detection.

CHEM400

For complex NMR analyses and structure elucidation. Three advanced spectroemeters are available.

  Bruker AV-400 Mhz high resolution (server am400.umd.edu):

  • Four different NMR detectors and temperature controller.
  • Default configuration is inverse gradient probe (BBI) with Z gradient.
  • Good for H-1 2D NMR or dynamic (DOSY) and kinetic projects.
  • Typical application for H-1-- C-13 2D ( HSQC, HMBC, and TOSY-HSQC).
  • Selective Shape pulse excitation (selective NOE, ROE).

Bruker DRX-500 MHz high resolution (server console500.umd.edu)

  • Four RF channels and seven different detectors, configured for a range of nuclei from O-17 to H-1.
  • Inverse probe H-1 (& F-19) with BB decoupling.
  • TXI probe H-1 with N-15 and C13 decoupling with triple gradients.
  • Inverse probe H-1, with Sn-27 and BB decoupling with Z gradient.
  • Best for X-nuclei detection with Bruker BBO probe.
  • Typical X-nuclei (C-13, Si-29, P-31, Pt, Pb, Na, Cs, F-19).
  • Typical applications ( DEPT, APT, H-X HSQC).
  • Selective Shape pulse excitation (selective NOE, ROE).

Bruker AVIII-600MHz (server CHEM600.umd.edu)

  • Higher field dispersion and highest sensitivity for polymers, carbohydrates, and natural products NMR projects or very dilute samples.
  • Four RF transmitters, configured for nuclei from O-17 to H-1.
  • Customed high sensitivity C-13 Detector.
  • Broad band probe with H-1 decoupling with autotune
  • Inverse probe H-1 (& F-19) with BB decoupling.
  • Selective Shape pulse excitation (selective NOE, ROE) at higher field dispersion.
  • Best for H-1 2D NMR or dynamic (DOSY) and kinetic projects.
  • Typical application for H-1-- C-13 2D ( HSQC, HMBC, and TOSY-HSQC).
