A T-T* measurement which permits speciation of different components with restricted mobility in samples where a T-Tmeasurement is impossible is disclosed. Tracking the T-T* coordinate, and associated signal intensity changes, can reveal additional structural and/or dynamic information such as phase changes in rigid/semi-rigid biopolymer samples or pore level changes in morphology of the water environments in cement-based materials. In another aspect, the T-T* measurement may also be employed to discriminate composition in solid mixtures, a very significant analytical problem in industry. In a further aspect, the T-T* measurement has particular value in permitting a simple assignment of Tto different T* populations.

Method and apparatus for T-T* relaxation correlation magnetic resonance measurement of materials

Method and system for determining a confinement size in a porous media, including subjecting the media to a substantially uniform static magnetic field, applying a magnetic resonance pulse sequence to the media, detecting magnetic resonance signals from the media, determining non-ground eigenvalues from the magnetic resonance relaxation spectrum, and determining a confinement size of the media from the eigenvalues.
