Nuclear Magnetic Resonance Spectrometer Facility

The Facility

The NMR spectrometer facility has one instrument available for use located in SRTC B2.

The 400 MHz spectrometer is available for “walk-on” use once the user has been trained by the facility and is run using an automation program. Only tubes rated for 400 MHz or higher may be used with this instrument. We recommend Wilmad 507-PP-7 (or equivalent) tubes. Lower quality tubes can damage the instrument. For this reason, those found using lower quality tubes (such as disposable tubes) will have their accounts suspended. During the hours of 9 AM - 6 PM, only short experiments (i.e., <20 min.) may be run. Between the hours of 6 PM and 9 AM, longer experiments (for example ~1 hour long carbon experiments) may be conducted, but please be considerate of others if there is high traffic at that time! Users are responsible for backing up their own data; the NMR facility is not responsible for maintaining data or for lost data. NMR sample tubes must be removed from the facility within one working day; individuals repeatedly leaving samples behind will have their accounts suspended, as this is a safety hazard. Please note that unused accounts are periodically removed from the system; if your account has not been used in a while (~1 year or more), we recommend that you contact the facility to check on the status of your account to ensure uninterrupted access to the instrument.

A 600 MHz spectrometer is not currently available, but we look forward to including one again in the future. 

Reservations:

For more information, please contact chem-nmr@pdx.edu. Please note that instrument reservations should be requested at least two business days in advance. NMR reservations must be canceled at least 24 hours in advance to avoid being charged for the reservation.

Training:

Training sessions should be requested a minimum of 1 week in advance. Depending on the type of experiments you intend to conduct (automated NMR/manual NMR) the training differs in length. Please see the training rates.
