Plastics, adhesives, and sealants as well as other MR-visible materials can be analyzed and characterized nondestructively by the Fraunhofer EZRT Polymer-Profiler program. The software, developed for the mobile MRI systems of Pure Devices GmbH, uses dedicated hardware for this application, which ensures outstanding sensitivity. The signals are measured with magnetic fields and high-frequency radio waves. They are then processed and displayed. Changes to the material, such as those caused by chemical, thermal, or aging processes, affect the MR measurement signal so that actions with regard to quality assurance or process regulation can be taken in a timely manner.
