  • Composite FID-CPMG process for fast relaxing media determination
    Patent number: 10782257
    Abstract: An apparatus, method and computer program for characterising samples using NMR. The apparatus includes a pulse sequence generator; and a response detector. The apparatus is configured to generate transverse and refocusing pulses and to record the decay response of a sample following a transverse pulse and echo response at least once after at least one refocusing pulse in order to enable determination of at least one relaxation time of the sample. In this way, sample or sample components with short relaxation times may be characterized.
