International Workshop Dispersion Analysis and Material Testing in Berlin, March 7-8

The scientific committee, chaired by Prof. Dr. Lerche, has selected topics for this year’s conference, being of interdisciplinary interest for the academic audience as well as for the industrial community.
Dispersions of nanoclay particles in dilute dental adhesives can be stabilized against undesirable fast sedimentation by surface modification using polymers. The real-time settling behaviour was analytically monitored using the Separation Analyser LUMiReader® as presented in a talk by the Persian Polymer and Petrochemical Institute.
Polymeric nanodispersions are the basis of a large variety of products in cosmetic, chemical, pharmaceutical, food industries. The correlation between dispersibility and functional performance is discussed in the presentation by National Taiwan University of Science and Technology. Similar issues are answered by researchers from Georg Simon Ohm University of Applied Sciences, Nuremberg.
Magnetite and magnetic nanoparticles are in focus of two presentations. Charité - Universitätsmedizin Berlin is investigating blood; the talk given by TU München puts the focus on coated magnetic nanoparticles for skin cancer therapy and on the influence of the surface modification of colloidal stability and particle size distribution.
Premium Ingredients from Spain coped with the challenge to characterize cacao particles in a smoothie. First, the Dispersion Analyser LUMiSizer® determined the hydrodynamic (in-situ) density of the dispersed cacao, since the dry density does not allow conclusions on the smoothie properties. In a second step the particle size distribution was determined according to ISO 13318, as one process parameter for product development.
The measurement of high concentrated industrial pigment pastes by various instruments is in focus of the contribution by iSL-Chemie, Germany. Particular attention is paid to the direct and accelerated separation stability characterization according to ISO TR 13097 using LUMiFuge®. In combination with other analytical data optimal production parameters are defined.
During the second day different application courses will take place following customers’requirements, including the use of the multiwavelength-LUMiSizer®.
