Huinink, H.P. Erich, S.J.F. Adan, O.C.G. Publication year 2021 Abstract An improved High-Speed NMR profiling method is introduced that enables to measure capillary action in thin, non-transparent porous media. Liquid profiles can be measured as fast as 10 ms with a spatial resolution of 14.5 µm. Capillary absorption of microliter-sized droplets into non-transparent nylon-6,6 porous membranes was studied. In nylon-6,6 sharp fronts obeying a 1D-Darcy model were observed. In paper uptake did not follow this model: retardation in uptake, broader fluid fronts and swelling was observed. These measurements nicely demonstrate the possibilities and versatility of the developed method.
