Nuclear Magnetic Resonance (ULUND)
NMR
Description
DESCRIPTION OF THE FACILITY
NMR equipment dedicated to studies of structure and dynamics in soft matter is available at Physical Chemistry, Lund University. The instruments are Bruker Avance-II spectrometers operating at magnetic fields of 4.7 and 11.7 T, corresponding to 1H resonance frequencies of 200 and 500 MHz.
The instruments are typically used for:
- Determination of translational self-diffusion coefficients, giving information on hydrodynamic radius, self-assembly, and confinement.
- Amphiphile phase behavior studies based on 2H or 13C solid-state NMR.
- Measurement of millimeter-scale molecular transport using spectroscopic NMR imaging.
- Order parameter profile determination using 1H-13C solid-state NMR.
POSSIBLE INSTRUMENT CONFIGURATON
The instrument can be run in different modes:
- Diffusion and imaging: Magnetic field gradients are used to encode the NMR signal for spatial position or displacements.
- Solid-state: Magic-angle spinning and high-power radiofrequency pulses yield high-resolution NMR spectra for solid and anisotropic liquid crystalline samples.
AVAILABLE SAMPLE ENVIRONMENT
Standard NMR tubes
TEMPERATURE RANGE
Measurements can be performed at temperatures ranging from 0 to 70ºC.
STABILITY
The temperature is controlled via a Eurotherm unit to an accuracy of 0.1 ºC.
PRESSSURE
Measurements are performed at ambient pressure.
MAGNETIC FIELD
Measurements are carried out at the magnetic fields 4.7 or 11.7 T given by the NMR magnets.
LOCATION
Facility available at Univ. Lund, Sweden
