Method and device for non-destructive analysis of polymeric samples using magnetic resonance sensors

The invention relates to a method for analysing a polymer sample (2) with nuclear magnetic resonance (NMR), the method comprising the following steps:providing a polymer sample (2);tempering a polymer sample (2);measuring a surface temperature of the polymer sample (2);subjecting the polymer sample (2) to a magnetic field of a magnet (4);applying a radiofrequency pulse sequence to the polymer sample (2);obtaining a radiofrequency signal response from the polymer sample (2);determining a microstructure-dependent parameter of the polymer sample (2) on the basis of the signal response.
