Pure Precision: PhD for Sara Schäfers Research on New Sensors to Safeguard the Quality of Ultra-Pure Water

Monitoring What Cannot Be Seen

In her dissertation, Sara Schäfer focused on the development and testing of two novel sensor systems designed for the continuous monitoring of ultra-pure water, also known as reinstwater. These sensors enable the real-time measurement of critical parameters, including total organic carbon (TOC) and dissolved ozone—both key indicators of water purity.

The main achievement of her work lies in enabling reliable online monitoring, allowing even the smallest, otherwise undetectable impurities to be identified immediately. This represents a significant step forward in maintaining stringent quality control in sensitive applications where water purity is crucial.

Doctoral Defense in Essen

Sara Schäfer defended her dissertation in Essen. The examination committee included Prof. Dr. Torsten C. Schmidt as supervisor and first examiner, Prof. Dr. Peter Kaul (H-BRS) as second examiner, and Prof. Dr. Erna Wieduwilt as chair of the examination board.

Career Start in Medical Quality Management

Following her successful doctorate, Sara Schäfer has begun her professional career as a Quality Management Officer in the field of virology at the University Hospital Bonn (UKB), where she contributes her expertise to ensuring high standards in medical diagnostics and research.
