NMR Sample Changer Rules

  1. BE NICE! The autosampler is a shared resource. Please be considerate to others when using it.
  2. The sample changer normally operates on a first-come, first-served basis (FCFS). Do NOT attempt to circumvent the system. Any attempt to run your sample out of order without staff approval may result in penalties up to and including termination of your facility access. If you have a legitimate research need to run samples with priority, contact us and we will move your sample to the head of the queue.
  3. Do NOT enter sample information into IconWeb if your sample is not ready.
  4. Do NOT exceed a total of 30 minutes per sample during the day. Experiments that exceed this limit must be submitted to the night queue, which operates between 8 pm and 8 am. If you have a legitimate research need to run long experiments during the day, contact us to get permission BEFORE submitting your experiment.
  5. Do NOT submit experiments before placing your sample(s) into the changer.
  6. Make sure you are in the CORRECT ROOM so you don’t take a sample out of the wrong spectrometer.
  7. Do NOT take out another user’s sample from the autosampler unless you are absolutely sure that you are in correct room and the sample is not queued to run or waiting to be submitted (see IconWeb instructions for details).
  8. If you break a tube or find a broken tube or pieces of glass in the sample changer, press the big, red emergency stop button on the changer’s control panel.
  9. NEVER try to fix the sample changer by yourself. If you notice a problem please contact us for assistance.
