Electrochemical Ammonia Monitor for Agricultural Operations

The U.S. Department of Agriculture (USDA) has identified the need for a practical analytical instrument for the detection of air emissions resulting from animal manure management systems. Based on this very important need, Giner, Inc. proposes to study and evaluate the feasibility of designing and fabricating a simple-to-operate, selective and solid-polymer electrolyte-based, thick-film electro?chemical ammonia sensor module (sensor cell with integrated potentiostatic control and signal-processing circuit) for continuous ammonia monitoring and demonstrate its successful operation. The sensor will be designed for accurate and rapid (less than 30 seconds for 90% of full response, T(90)) detection of ammonia concentrations in the range of 0 to 300 ppm and resolution of 0.1 ppm or less.
