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.
- All users must follow the scheduling restrictions of the NMR lab and register in advance.
- 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.
- Any error message must be reported.
Facility Schedule (maintenance)
Liquid nitrogen fills are performed once a week:
- AVIII-300, AVIII-400 and AV IIIHD-500, Sunday morning (08:00-10:00)
- Liquid helium fills normally render the instruments unstable for a few hours. Fills generally occur once every 3 months (300, 400 and 500 MHz).
A guide for new NMR Users
Our high-resolution NMR spectrometers are normally operated in two ways:
- By trained users: The AVIII-300, AVIII-400 and AVIII HD-500 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 special permission for scheduling time on the instruments (via Internal Services) as well as a userid for login to the instruments. If advanced experiments or analysis is required, it is recommended to consult the NMR lab staff.
- As a service: A liquid NMR service is provided on the AVIII HD-500 and AVIII-400 both for WIS staff (Internal NMR Services) as well as for external users (External NMR Services).
