This course provides a general overview of the characterization methods for particle and particle systems. In the first the parameters describing size, shape and arrangement of small particles are defined, and the statistics of small particles is explained in great detail, including quantiles, mean values, moments and moment ratios. In the second part the different particle characterization techniques are considered, from sedimentation techniques to laser diffraction, image analysis, X-ray diffraction adsorption methods and less common techniques. The last part of this subject concerns disperse systems. The course is appropriate for students of all subjects and can be recommended to all those whose work requires the charactzerization of particle systems and microstructures.

Students will be able to:
correctly use all concepts related to particle size and shape, correctly interpret size distributions, use the correct terminology for the presentation of results and understand the theoretical fundamentals of common characterzation methods to the degree necessary to take full advantage of the current special literature in the field.
