We have a few of the new Bruker Avance Neo consoles in the NMR Facility; Gauss, Hertz and Tesla for solution NMR so far. Bruker have included the Autocalibrate sample and software in the sale of all new consoles. This program calibrates the temperature correction, 1H 90 degree pulse and 13C 90 degree pulse. It will also ensure the shimming is optimal and the quantitative capabilities of the spectrometer are meeting the Bruker specs.

The only aspect of Autocalibrate that will affect you as a user is the temperature calibration.

The temperature correction on the three machines is now checked on a weekly basis. As you can see the large temperature reading has been corrected and the small number under it is the number read off the Bruker thermocouple. If you are concerned about replicating a particular temperature the external thermocouple can still be used to obtain a particular value.

Temperature corrections are based on gas flow values and BCU settings and valid between 15 ^oC and 35 ^oC. If your desired temperature is outside of this range or you are using different settings please talk to Facility staff. We can create a new temperature correction set for you or you can simply disable the correction for the duration of your experiment. Please remember to restore the default settings after your booking.
