POLICIES & TRAINING

General policies

  • No food or beverages near the spectrometers or workstations.
  • No sample preparation in the NMR Lab.
  • Do not leave your NMR tubes in the NMR Lab.
  • If a sample breaks in the magnet, contact the NMR lab staff immediately so the probe can be cleaned. This will minimize probe damage from corrosive solvents.
  • All users must follow the scheduling restrictions of the NMR lab, and register in advance.
  • All 300MHz-users must sign the spectrometer log-book.
  • Non-standard experiments/ probe change must be scheduled with the NMR lab staff in advance.
  • Do not change any NMR probes or reconnect any RF cables.

Facility Schedule (maintenance)

  • Liquid nitrogen fills are performed once a week:
  • AVIII-800, Monday morning (08:00-10:00)
  • AVIII-300, AVIII-400 and AV-500, Monday morning (08:00-10:00)
  • Liquid helium fills normally render the instruments unstable for a few hours. Fills generally occur once in 6 weeks (800 MHz) to once in 3-4 months (300, 400 and 500 MHz). If you are scheduled for an instrument on that day, a warning note will appear.

A guide for new NMR Users

Our high-resolution NMR spectrometers are normally operated in three ways:

  1. By trained users: The AVIII-800, AV-500 and AVIII-400 instruments are accessible to anyone who has been trained on their use by the NMR lab staff, performing work for their own research groups. Each authorized-user account is given a special permission for scheduling time on the instruments (via Internal Services) as well as a userid for login to the instruments.
  2. As an open access:First-come first-served open access: As an open access: A short training session allows members of the Organic Chemistry Department to run samples on the AVIII-300. Booking 20-minute sessions on the AVIII-300 is done on site, on first-come first served basis.
  3. As a service: A liquid NMR service is provided on the AV-500 and AVIII-400 both for WIS staff (Internal NMR Services) as well as for external users (External NMR Services).
