Measurements

•    Static experiments between -130 and 130ºC.
•    MAS experiments between -70 and 90ºC.
•    Decoupling experiments for proton and fluor.
•    CPMAS experiments with decoupling.
•    MQMAS experiments for quadrupolar nuclei.
•    Measurement of diffusion coefficients for proton, lithium and sodium.
 

Equipment

• NMR Spectrometer AVANCE II (BRUKER), 9.4 Tesla magnet.
• MAS probes for different spinning speeds for the study of a wide range of nuclei:

• Static probe for the study of single-crystal for nuclei 31P-109Ag (162-18 MHz).

Allowed Samples

Samples must be provided preferably grinded. If necessary, further grinding will be carried out by the NMR facility staff unless opposite specifications are detailed.  
The optimum amount of sample to run MAS NMR experiments is as follows: 
- 7 mm. rotors: 200-400 mg. 
- 4 mm. rotors: 100-200 mg. 
- 2.5 mm. rotors: 30-50 mg. 
The concentration of ferromagnetic and/or paramagnetic species can not be over 5% by weight. If present, it is mandatory to indicate its nature and approximate concentration. The user will be responsible for the damages caused to the spectrometer by ferromagnetic and/or paramagnetic impurities which are not reflected in the request form.
