Boron-11 NMR

Dear Bruker Users,
We have a DPX400 with a 5mm VSP probe on which I
regularly record 11B spectra. For some reason our inorganic chemists
seem to think they can do a better job themselves, so they want limited
access to the DPX for that purpose. It seems to me that the 'quicknmr'
subsystem of XWINNMR provides the least hazardous route for limited
access to the DPX, since we don't have a sample changer, but I have
concern about the ability of XWINNMR to phase- and baseline-correct 11B
spectra automatically.
So far I have not recorded any 11B spectrum which could
be successfully phase-corrected automatically, either with 'apk' or
'apks'. Likewise, even with the phase correction carefully done by
hand, none of these spectra have come out of 'abs' better than when
they went in (using the default 'abs' parameters). I know I would be
better off with a probe optimised for 11B, but we've already had a grant
application for one of these turned down, so it's not an option at
present.
Has anyone any suggestions about how I might overcome
this processing problem? Allowing these people full access to the DPX is
something I would _not_ do, since the whole thing is so flaky and
insecure. Maybe remote processing is the only way. What do you do?
Thanks in advance,
Alan
