A system for measuring nuclear magnetic resonance spin-lattice relaxation time Tand spin-spin relaxation time Tof a sample includes a source of a substantially uniform magnetic field Bfor immersing at least a portion of the sample; a nuclear magnetic resonance excitation and detection system constructed and arranged to excite at least a portion of the sample with a plurality of nuclear magnetic resonance pulse sequences, each applied with a repetition time that is preselected to be sensitive to a Tvalue of at least a portion of the sample, and to detect nuclear magnetic resonance emissions from the sample in response to excitations to provide a plurality of detection signals; and a signal processing system configured to communicate with the nuclear magnetic resonance excitation and detection system to receive the plurality of detection signals.
