Selected applications of spatially resolved NMR are presented, which demonstrate the use of the method for investigating applied topics relevant to polymer and materials science. Examples are given for imaging of rigid, soft, and fluid matter. They include characterization and interpretation of electrical aging in poly(ethylene), cross‐link density at the interface of covulcanized elastomer sheets, and cross‐filtration in hollow‐fiber filter modules. A novel NMR detector, the NMR‐MOUSE, has been developed for process and quality control by relaxation measurements. Its use for non‐destructive determination of the glass‐transition temperature by room temperature measurements on elastomer samples is demonstrated.
