Bruker 400 MHz (b400)

in CLB110

The probe is tuned automatically. You can use this instrument for observation of other nuclei with good sensitivity, like F19, P31, B11, Al 27 or N14. For other heteronuclei, I recommend using the b600.

F19 is on the low-band coil, therefore after tuning to F19 you have to tune back to C13 (and not to H1 as on the Varian instruments). It has the best signal-to-noise ratio for F19 of all the instruments in the Center. This configuration allows for F19-H1 correlation experiments, like HOESY, or observing one of these two nuclei while decoupling the other.

The instrument is appropriate for running 2D experiments with pulsed-field-gradients and shaped pulses, as well as selective 1D experiments, as long as the amount of sample and the chemical shifts resolution are not a problem. Ask here for a training.

The temperature range is from room temperature to 150 C.
