Facilities
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 1 H/ 13 C/ 15 N 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.
(ii) Varian Inova-600
This 600 MHz spectrometer was installed in 1999. It 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 will be installed in 2007
(iii) Bruker Avance-600
This 600 MHz spectrometer is made up of a Bruker Avance console that was installed in September 2003 together with an Oxford magnet that was originally part of our 1989 spectrometer. The resulting spectrometer is equipped with four RF channels and single-axis pulsed-field gradients. A 5mm 1H/13C/15N triple-resonance PFG cryoprobe was installed at the beginning of March 2004. A conventional 1H/13C/15N triple-resonance PFG probe is also available.
(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. A conventional 1H/13C/15N triple-resonance PFG probe is also available.
