Liquid chromatography is a unit operation with a high separation efficiency that is based on a homogenous structure of the packed bed. Because of this, the work is devoted to study the suitability of two different, non-invasive approaches for the evaluation of the packing properties. The first approach comprised the investigation of the suitability of tomographic measurement techniques to yield relevant information about the packing structure. On the basis of experimental investigations it could be shown that computed tomography measurements as well as nuclear magnetic resonance studies are suited to get information about the properties of the packed bed. The second approach was about the influence of irregular column packings on the signal...
