New Equipment:
Bruker Avance-600
The 600 MHz spectrometer is used for solution NMR and solid CP-MAS experiments. It is equipped with a 4-channel TBI probe which can bo H / H2 / C / BB(P31-N15).
Bruker Avance-400 (automatic sample changer,
BB auto tuning)
The new 400 MHz spectrometer is used for automated
run in solution NMR, Diffusion experiments, low concentration, Complex samples
etc...
- It is equipped with an automatic sampler device (50 samples)
- Any 1D or 2D NMR experiments can be programmed to run automatically. The
user can download their data from the network.
- The probe used (Broadband inverse) is capable of proton observe (high frequency
coil) and can also observe any nuclei from Phosphorus down to Silver (low
frequency coil): all that with automatic Tuning and Matching device.
Bruker Avance-500 (DRX)
The 500 MHz spectrometer is used for:
- high field low gamma nuclei MAS experiment.
- 2D (and 3D) work on complex samples
- Low concentration/high resolution need
- Diffusion experiments
- F19 is also possible using the BBFO probe.
This spectrometer is a narrow bore magnet (11.7 Tesla) a PC as host compute running TOPSPIN. It is equiped with gradient pulse capability on
three orthogonal axes and have all hardware and software necessary for multi-dimensional,
multi-resonance experiments. It is equiped with variable temperature capability
and an FTS air system allow to control the temperature in the range of 0C without
the need of using liquid nitrogen.
The 500 MHz spectrometer is 2-channel broadband console equiped with a variety
of probes.
- A 5mm proton and X-nucleus detection (inverse) (BBI), equipped with actively
shielded gradient coil (3-axis: X, Y, Z). The broadband capability of that
probe ranges from P-31 to Ag-109.
- a 5mm BBFO probe with auto tuning and matching accessory
- There is also be a probe for CP-MAS applications and a HP N15-P31 (low gamma
nuclei MAS).
Bruker Avance-400
The 400 MHz spectrometer is used for:
- less demanding proton resolution work (1D and 2D)
- all 2D (less demanding samples)
- F-19 observation
- Broadband work in NMR
- variable temperature
- Selective experiments (1D-TOCSY, 1D-NOE ...)
The 400 upgrade was completed on December 1998. The console of that spectrometer
is 2-channel broadband.
Probeheads:
- A BBFO probe with auto tuning and matching capability and actively shielded Z-gradient coil.
- A QNP probe that is capable of doing proton and either phosphorus-31, Carbon-13
and Fluorine-19 is available. One very nice feature of the QNP probe is it's
capability of doing Fluorine-19 with or without proton decoupling, and proton
NMR with or without F-19 decoupling.
- A 5mm proton and X-nucleus detection (inverse) (BBI), equipped with actively
shielded gradient coil (Z-axis). The broadband capability of that probe ranges
from P-31 to Ag-109.
- The older 10 mm BB probe covering frequencies from P-31 to Ag-109 is also
available.
Bruker Avance-300
The 300 MHz spectrometer is equiped with a QXI probe (with shielded Z-gradient).
The QXI probe is an inverse probe allowing the observation of Proton, Carbon-13,
Phosphorus-31 and Nitrogen-15.
The 300 MHz spectrometer is used for (for planning purpose, the experiment
time needed to run the experiment is shown in bracket):
- Routine proton (2 min.)
- Routine COSY (5 min.)
- Routine 2D-TOCSY experiment (5 min)
- Routine HMQC (Proton-Carbon 2D heterocorrelation) (5 min)
- Routine HMBC (Proton-Carbon 2D heterocorrelation using long range coupling)
(20 min.) (experiment can be shortened to 6 min if needed)
- Routine P-31 (2-20 min. - depends on concentration)
- Routine C-13, DEPT, and J-MOD (20 min - depends on concentration).
A "Six-Pack" autosampler can be used in automation mode.
