Interference and IR microscopy are so far the only two techniques, which allow the direct observation of the evolution of concentration profiles in the interior of zeolite crystals. In the present project they are applied for the investigation of intracrystalline transport diffusion in a series of zeolitic adsorbate-adsorbent systems. The observed transport properties are compared with the results of the diffusion measurements of the identical systems by the other techniques of the consortium. These investigations shall be accompanied by methodological developments of the techniques. They focus on a further enhancement of space and time resolution and sensitivity, as well as on an extension of the temperature range of the measurements.

干涉和红外显微镜是迄今为止仅有的两种技术，它们允许直接观察沸石晶体内部浓度分布的演变。在本项目中，它们被应用于一系列沸石吸附剂-吸附剂系统中的晶内输运扩散的研究。所观察到的传输特性进行了比较，由财团的其他技术的相同系统的扩散测量的结果。这些调查应伴随着技术方法的发展。它们侧重于进一步提高空间和时间分辨率和灵敏度，以及扩大测量的温度范围。
