There is much focus on emission of ammonia from farming industries. Ammonia is often difficult to measure because it sticks to almost all surfaces, which gives long response time when comparing different concentrations. Accurate and reliable sensors are important in order to quantify emissions.

The overall aim of the project is to develop a novel micro-scrubber miniaturised ammonia sensor using fluorescence detection. The project consists of the following activities: 1) Development of micro-scrubber design and configuration. 2) Development and test of a fluorescence analytical system. 3) Characterisation and validation of lab-on-a-chip sensor at laboratory scale. 4) Field validation and intercomparison test.

The sensor is developed for a low-energy hybrid ventilation concept and will be tested and applied for hybrid-ventilation livestock facilities. Furthermore, the sensor will be used to validate manure application techniques to minimise emissions of ammonia.
