The keynote An investigation on adhesion forces of particles on surfaces in centrifugal and magnetic fields by Prof. Nirschl of German Karlsruhe Institute of Technology, opens the congress, organized by LUM GmbH. Surface characterization of the particle itself becomes a more and more important topic industry. A Japanese scientist is discussing it on the example of the determination of the Hansen Solubility Parameters (HSP) by the Separation Analyser LUMiReader®. Nanoparticle reference materials are described by Russian researchers, the dispersibility of carbon black in n-alkanes by a representative of the University of Sheffield and the dispersing behaviour of carbon nanotubes a member of the Technical University Nuernberg. Lignite hydrocolloids are measured using a Dispersion Analyser LUMiSizer at Brno University of Technology, Czech Republic.
The characterization of colloidal particle aggregates is successfully performed by optical analysis in a separating centrifugal field, presented by the Technical University Dresden.
Further sessions of the congress are dedicated to emulsion characterization. Here, experts in Israeli pharmaceutical industry save time and money when using the accelerated separation in the Stability Analyser LUMiFuge for the development of a new drug.
A French workshop contribution gives proof of the stability analysis of aqueous dispersions for cosmetic and aerospace industries. Formulation development in pharmaceutical industry belongs to the important application areas of LUM customers. Novartis Pharma AG, Switzerland, reports on wet-media milled drug suspensions, Perrigo Israel Pharmaceuticals Ltd. about the LUMiSizer as bioequivalescence tool for nasal spray development.
Applications for LUMiSizer® and LUMiFuge®, proving the enormous potential of these innovative measuring instruments outside the fast stability testing and particle characterization, complete the workshop programme. For the first time, a LUM instrument is applied for the determination of biomechanical properties of bone samples, introduced by Charité-Universitätsmedizin, Berlin. Mechanical properties of sediments and filter cakes strongly depend on colloidal interactions between particles and influence the dewaterability of sludges and wastewater. New scientific findings are presented by the University of Leeds.
