500 MHz BBI-ATM Spectrometer - 'Glengrant' - Room B19
The Bruker Avance 500 BB ATM 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. The spectrometer is operated by trained users from various research groups. The probe is an ATM BroadBand type - which enables automatic tuning and matching of all broadband nuclei from Silver(47Ag) to Phosphorus(31P). This approach means that from insertion to removal of sample, there is no need to leave the operating workstation to tune the probe to your nuclei of choice. The magnet has been fitted with a sample changer - this allows users to run a series of samples during the day or overnight if required - the IconNMR automation software is configured to interface with the ATM probe to tune each individual sample. A box of spinners is available to borrow from the service staff in B28. This instrument is also set up with a nitrogen evaporating dewar unit to allow VT experiments down to -100C, as well as up to +130C. The magnet has been modified with an air system that keeps the bore tube and o-rings closer to room temperature during VT work - see the NMR service for details of this before running VT experiments.
As well as being ideal for multinuclear 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 booking sheet inside the door to B19. Please abide by the booking rules to ensure every user has a fair chance of getting a slot on the instrument.
