The AVIII has been having an intermittent error on sample insert/eject. I have been working closely with Bruker to troubleshoot this ongoing issue. If you find the system in error state (the SampleJet light flashing), please contact the NMR manager and leave the system alone. Do not attempt to recover a sample or fix the error. It is important that the manager is able to see the error messages and the orientation of the sample to the instrument in order to understand the problem. Please make sure to use high quality NMR tubes that are clean and unbroken. Make sure the cap fits snugly to the tube. If your NMR tube is poor quality this increases the chance for system failures. The tubes need to fit snugly into a spinner. Chipped, broken, or short tubes will be removed from the system and discarded.
Also, never manually turn the rack in the SampleJet. This can damage the motor.
I appreciate your help as we make sure the system is optimized to generate high-quality and high-throughput NMR data.
-TLY, manager
