M. Schelter, J. Zosel, F. Berthold, W. Oelßner & U. Guth
The anaerobic production of biogas from biomass is one of the most important pillars of renewable energy sources worldwide. This transformation is based on the complex teamwork of thousands of different microbes. The concentration of dissolved hydrogen is one of the key parameters known to indicate process stability limitations. In this work a measuring system for dissolved hydrogen in anaerobic biogenic media with high selectivity and sensitivity is presented, which provides high longterm stability and...
