Excessive use of nitrogen based fertilizers in agriculture represents an environmental hazard. Thus, analysis of soil water and groundwater has become an essential part of substainability and ecological preservation. On this account, the Multilyzer provides a suitable solution.
The Multilyzer is a microfluicid online measuring system for the determination of lowest concentrations of nitrate, nitrite and ammonium, all of which are essential components of the nitrogen cycle. The transportable system allows an online measurement and is driven by a 12 Volts battery. Consequently, conversion and degradation processes can be avoided, unlike the analysis in a local laboratory. The measurement is based on absorption and fluorescene spectroscopy. The complete device is developed at the Centre of Excellence Nanochem at OTH Regensburg including fabrication technologies, software and hardware controlling.
