The Centre is currently equipped with an 800 MHz spectrometer, a 700 MHz spectrometer and two 600 MHz spectrometers. The spectrometers are all equipped for 1H/13C/15N triple-resonance experiments with pulsed-field gradients and deuterium decoupling. Three of the spectrometers are equipped with cryogenically-cooled probes. A variety of Linux and Sparc workstations are available (with appropriate software) for data processing and structure calculations. Laboratory facilities are available to external users for preparation of samples.
i) Varian Inova-800
The 800 MHz spectrometer uses an Oxford 4.2 K magnet. The spectrometer has four RF channels and single-axis pulsed field gradients and is equipped with a cryogenically cooled 5 mm 1H/13C/15N triple-resonance PFG probe.
News.... The 800 will be receiving a new console and cryoprobe. The installation work will start on 30th May. Scheduled operation will resume as soon as possible thereafter.
(ii) Varian Inova-600
This 600 MHz spectrometer is equipped with four RF channels and single-axis pulsed-field gradients. It has 1H/13C/15N triple-resonance PFG probes for both 5 mm and 8 mm samples, and also a 5 mm 1H/13C/31P probe. Probes for X-observe experiments and for 19F/1H experiments are also available.
(iii) Bruker Avance-600
This 600 MHz spectrometer is made up of a Bruker Avance console together with an Oxford magnet that was originally part of our 1989 spectrometer. The resulting spectrometer has four RF channels and single-axis pulsed-field gradients and is equipped with a 5mm 1H/13C/15N triple-resonance PFG cryoprobe. This probe has a cryo-cooled C13 preamplifier, which makes it suitable for experiments that involve direct detection of signals from C13 nuclei.
(iv) Bruker Avance-700
Scheduled use of our new 700 MHz spectrometer started in May 2007. This spectrometer consists of a Bruker shielded magnet and an Avance II+ four-channel console, together with a 5mm 1H/13C/15N triple-resonance PFG cryoprobe with cooled C13 preamplifier. Like the Avance-600, this probe has a cooled C13 preamplifier and so is suitable for direct detection of C13. A Bruker SampleJet automatic sample-changer was added to this spectrometer in November 2011.
