Nondestructive characterization of polymers with NMR in one-sided access technique

Besides the absence of defects and the geometrical properties, the quality controlling characteristics of polymers are based on their microstructure. Up today, there is a considerable demand on methods capable to characterize these properties in a nondestructive manner. Nuclear magnetic resonance (NMR) is known to be a versatile analytical tool, which is highly sensitive to micro-structural features of organic matter. Traditionally, NMR equipment is used for off-line polymer analysis in the laboratory. This conventional NMR equipment can be operated only with small samples. In contrast, the one-sided access (OSA) NMR technique does not restrict the maximum sample size and offers the capability for nondestructive applications on large components and even on stationary objects.
