Hi, friends:
I did some 11B solid-state MAS NMR on our MSL-300 with boron nitride
stator, got good results. The signal of boron in the stator should be very
broad and decay very fast (due to non-spinning), one solution is to insert a
acquisition delay after the pulse. 100us delay was enough for my
experiments, it reduced the background signal significantly.
