ZetA Partikelanalytik GmbH was founded in 2007 as Spin-Off from Prof. K.K. Ungers working group from Mainz University. ZetA Partikelanalytik is a service provider with special expertise to help solving problems related to surface, porosity and morphology of materials. ZetA Partikelanalytik is an independent service lab with own facilities outside the campus and was founded with the aid and guidance of the FiTOUR-programme by Rhineland-Palatinate-"Ministry of Economics, Traffic, Agriculture and Viniculture". All our activities are based upon a profound knowledge from long-term activities in industry-related academic research, enabling us to serve customers worldwide as very effective partner in materials development.
We provide our customers not only with measurements and data but also with relevant scientific background information for the evaluation and correct interpretation related to their specific problem. This means that customers can fully concentrate on their specific topics - while we help in finding a solution for a specific challenge.
Dr. Zöfre Bayram-Hahn, general manager
Dr. Bayram-Hahn conducted her PhD-Thesis under the guidance of Prof. K.K. Unger at the Institute of Inorganic Chemistry and Analytical Chemistry of Johannes Gutenberg University of Mainz, which she finished 2007. Her main research subject was the synthesis, characterization and optimization of polymer-coated stationary phases for the separation of biopolymers by maintaining their biological activity. This was achieved via systematic variation and optimization of polymer-load and hydrophilic/hydrophobic properties of the polymer-layer. For optimum reproducibility and comparability of the results she developed well-defined protocols for performing characterization tasks, being an important part in lab services offered by ZetA Partikelanalytik. This includes chromatographic methods like ISEC (pore size determination), frontal analysis by staircase-method (adsorption isotherms) or H-vs.-U-curves (mass-transfer based on Knox-equation or van-Deemter) and test for biocompatibility of chromatographic media (relative enzymatic activity).
Mrs. Bayram-Hahn is your contact person at "ZetA" with a special expertise for chromatographic sorbents.
Dr. Andreas Hahn, general manager
Dr. Hahn conducted his PhD-Thesis under the guidance of Prof. K.K. Unger at the Institute of Inorganic Chemistry and Analytical Chemistry of Johannes Gutenberg University of Mainz, which he finished 2003. His main research subject was about the investigation of the nucleation and growth process of spherical nano-sized porous silica beads and MFI-zeolites. Therefore he modified and simplified the synthesis route for MFI-zeolites to work under atmospheric pressure to achieve optimum sampling conditions. This enabled the gathering of interesting in-sights in the nucleation process - mainly by employing specific online-investigations based on neutron- and synchrotron-scattering techniques. He joined Prof. Ungers working group in 1995 and was actively involved in several industry-related research projects covering the whole range of heterogeneous catalysts from synthesis and characterization to the application of sorbents. In his recent project he was investigating materials for the use in heat-storage devices.
Mr. Hahn is your contact person at "ZetA" with a special expertise for inorganic sorbents for heterogeneous catalysis (zeolites, MOFs, silica etc.) and for materials with active surfaces.
