Before you call B
RUKER, or if you have no idea how to address the problem, an-
swer the following questions (see also "CryoProbe service" on page 87
):
- which errors or warnings appear?
- what are the readings of the pressure gauges etc.?
- which parts seem to be ok/not ok?
- how did the failure occur and what happened before the failure?
- which experiment did you run or intend to do?
- is the sample special, did you do a similar NMR measurement on the
sample before either with the CryoProbe, with a conventional probe, or on
another spectrometer?
Simple checks:
- try to reproduce a standard spectrum you successfully recorded not long
ago with the same sample and identical experimental parameters.
- replace the CryoProbe with a conventional probe and run the experiment
again.
