Abstract: A new design for an in-situ combination of NMR and rheological measurements is presented. The NMR instrumentation is based on a Bruker Minispec spectrometer with a home-built magnet system consisting of 64 permanent magnets in a so-called MANDHALA arrangement. This magnet reaches a flux density of about 0.23 T, corresponding to a H-1 NMR resonance frequency of about 9.5 MHz. The NMR apparatus is combined with a Scarabaeus SISV50 instrument with modified sample cells to allow synchronous in-situ rheological and NMR measurements. This unique instrument and first exemplary measurements of a curing epoxy resin and the vulcanization of a rubber sample are presented.
