The Center has two groups of high resolution NMR spectrometers to meet your
needs:
For large numbers of NMR samples
that require fast turn-over and quick analyses, the Center is equipped with
two high throughput NMR spectrometers both at 400MHz field strength. They
are good for product screening with samples of moderate concentrations. Click
for more information.
For the best result, we recommend
you plan and carry out your project with the latest Advanced spectrometers
in the Center.
Pending on the nature of the nuclei under study, one can select any of the
three NMR spectrometers, from 400MHz, 500MHz and 600MHz field strength. Details
of the capabilities are listed below. Optimization and fine tunings are routinely
carried out for all NMR measurements. All measurements can be carried out
at controlled temperature. Advanced reservation is highly recommended.

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).

(server console500.umd.edu)
- Four RF channels
and seven different detectors, configured for a range of nuclei from
O-17 to H-1.

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).

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).
