Access and reservations

The NMR facility provides access to its instrument to University staff in two different ways:

- Open-access service: from 8am to 4pm, samples may be submitted to the facility staff for the collection of common 1D NMR spectra under automation for routine structure characterization. Acquired data are returned to users for analysis, but you also may seek the assistance of the NMR staff as necessary.

The sample must be brought to the laboratory paired with the submission ticket properly filled out.

Attention must be paid to the preparation of the sample to ensure straightforward automatic operations and good quality spectra.

1. 5 mm tubes must be checked for cracks and for scratches and discarded if necessary

2. Use the proper amount of material. 1-10 mg are typically required for 1H spectra. Remember that an overly concentrated sample will give a quick 13C spectrum, but may lead to difficulties in shimming and broad 1H lineshape.

3. Use the proper amount of solvent. 0.6-0.7 ml of deuterated solvent are typically required to match the sample depth gauge. Less solvent will make more difficult for the spectrometer to lock and shim; more solvent will dilute your sample and waste solvent.

4. Check that there is no precipitate in the tube. This would complicate the automatic shimming procedure, worsening the condition of the instrument even for subsequent samples.

- Bookable: from 4pm to 7am, the instrument can be reserved to operate in "hands-on" mode, after consulting the availability on  Google Calendar. This mode is intended for more advanced studies and experiments, which may need more time to be set up and run. Users must be trained before using the instrument. The facility staff remains available for doubts and needs.

We invite you to read the Regulation and Tariff, before making a reservation.

NMR analyses are not exclusive for internal research, service is provided to external institutions as well. For information, refer to the Analyses page or write an e-mail to fe.rossi@unito.it
