500 MHz AVIII HD Smart Probe Spectrometer - 'Glengrant' - Room B19
The Bruker Avance III HD 500 MHz Smart Probe spectrometer is housed in B19, at the other end of the room from the Avance 500 TCI instrument. This is one of our most heavily used instruments, performing a large number of routine acquisitions as well as more specialised experiments. The spectrometer is operated by trained users from various research groups. The probe is a BBO Smart Probe type which is ideal for multinuclear work.
Note that this probe has just been returned from repair; this has in principle restored full multinuclear operation however not all nuclei are currently available. Those in bold have been tested, the rest should work in principle once we have redone the calibration. If you need any currently untested ones check with us, we should be able to sort this out quickly. Note that a software issue prevents us running 17O, 15N, 14N and 109Ag at the moment, we hope this will be fixed very soon. This page will be updated as we recalibrate more nuclei.
The full list of nuclei that we hope to have set up on this spectrometer is:
1H, 2H, 7Li, 11B, 13C, 15N, 17O, 19F, 23Na, 25Mg, 27Al, 29Si, 31P, 33S, 35Cl, 39K, 47Ti, 49Ti, 51V, 55Mn, 59Co, 67Zn, 69Ga, 75As, 77Se, 87Rb, 95Mo, 109Ag, 113Cd, 119Sn, 125Te, 133Cs, 139La, 195Pt, 207Pb
All of these nuclei are in principle available to observe, however it is important to note that some of them have only been run with a specifically prepared test sample, not a real world example. Please see the NMR Facility team in B28 if you are unsure whether your sample is concentrated enough to observe in a reasonable time.
This instrument is also set up with a BCU Chiller unit to allow VT experiments down to about -50C. This means that control of sub-zero temperatures can be handled from the operating workstation through the "edte" window, without having to attach and detach nitrogen dewars. Please see the NMR team if you have not run VT experiments before.
As well as being ideal for multinuclear and variable temperature work, the instrument will handle routine 1H and 13C acquisitions as well as COSY, HMQC/HSQC and HMBC on reasonably concentrated samples. However, we recommend that researchers requiring a large accumulation time to achieve a reasonable 13C spectrum on this instrument should consider the time saving and quality improvement offered by our Service 500 Cryoprobe system.
Time allocation on this instrument is by the online booking system available here. Please abide by the booking rules to ensure every user has a fair chance of getting a slot on the instrument.
