The AVIII 400 NMR-Saffron is down due to a hardware failure. Because there is a chance of sample breakage – the system will be unavailable until the issue is resolved. Please plan on the system being down for a few days. The 400 MHz in Evans is available (quick walk in the cold weather) or have a labmate run samples on the 600 MHz.
Problem details: The SampleJet ‘arm’ falls after the sample is inserted. When the sample is ejected, the NMR tube gets pushed down into the spinner. At this point, the system fails to pick up the sample and stops the run. So far, this has not broken an NMR tube, but it perhaps might. Bruker has been contacted to determine the source of the problem.
Update 1.5.2018: The system is now available.
