Preparation of agarose gels as reference substances for NMR relaxation time measurement. EEC Concerted Action Program.
A standard method has been developed for the production of reference materials for NMR relaxation time measurement. These are based on agarose gels doped with gadolinium. The reproducibility and temporal stability of the gels have been found to be excellent. Electron microscope studies have shown good homogeneity. The relaxation behavior of such gels has been mathematically modeled with good agreement with experiment.
