# ¹¹B NMR in a borosilicate tube

I'm just wondering, if one were to run a $\ce{^{11}B}$ NMR on a boron containing sample in a borosilicate tube, how could we separate the spectra of the tube and the sample?

Apart from using a different tube - Perhaps through a pulse sequence like BIRD for $\ce{^1H/^13C}$?

Or decoupling - which I've only just started to learn about and don't really understand?
