Have a look inside : A magnetic resonance imaging (MRI) procedure allows the distribution of paramagnetic metal‐ion complexes inside catalyst bodies to be probed in a quantitative manner, without influencing the sample during measurements (see picture; blue: high 1 H NMR signal (low Co 2+ concentration) red: low 1 H NMR signal (high Co 2+ concentration)).
