Varian Infinity Plus 400WB
This
solid-state NMR spectrometer is a 3 channel instrument equipped with six probes.
A high-speed (3.2 mm, 25 kHz) double resonance HX probe, three HXY probes
(4.0 mm, 7.5 mm and 9.5 mm) and a HFX (5.0 mm) for triple resonance experiments.
As well as a double resonance HX solenoid probe (5 mm and 10 mm inserts) for
static samples. Variable temperature experiments are available on all probes.
Varian Inova 600
This
spectrometer is our premier research spectrometer. It has 4 channels (HXYD)
and triaxial gradients allowing for ease of structure determination of chemical
and biochemical systems using multidimensional NMR techniques on both a z-gradient
triple resonance inverse HCX probe and a direct observe XH probe. Routine
solid-state experiments are also available using a 3.2 mm HXY probe. Variable
temperature experiments are available, both above and below room temperature
down to as low as -30oC without the need of cryogenic materials.
Varian Inova 400
This
spectrometer has 3 channels (HXY) and is equipped with a single axis z-gradient.
An autoswitchable 4-nucleus (HFCP/HFX) z-gradient probe allows for direct
and indirect multi-nuclear NMR experiments (e.g., 13C, 29Si, 31P, 77Se, 119Sn,
195Pt, etc.). Triple resonance experiments are available for inorganic complexes
using a HPX z-gradient probe and direct observation is also available using
a 10 mm XH probe. The variable temperature accessories for this instrument
have been optimized to allow for the running of long term low temperature
experiments (down to -90oC) with the minimum amount of cryogens needed.
This spectrometer is the departmental workhorse instrument. It is equipped with a 50-spinner sample changer and a 4-nucleus (HFCP) autoswitchable z-gradient probe. All routine 1D (1H/19F/13C/31P) and 2D (1H1H and 1H{13C}) experiments are run via automation at room temperature. This instrument runs the undergraduate service spectra.
