Principles of Operation in UV Nitrate Sensing Technology - Understanding NOM and Turbidity Corrections

Learn about groundbreaking UV nitrate sensing technology in this 18-minute conference presentation from the Georgia Water Resources Conference. Explore the operational principles of the YSI EXO NitraLED™ sensor, which employs optical absorbance for nitrate detection. Understand how the sensor addresses key challenges like turbidity interference from suspended particles and Natural Organic Material (NOM) interference in UV light ranges. Delve into the sensor's functionality, calibration processes, and data collection methods while examining the broader context of eutrophication, harmful algae blooms, and their health impacts. Master the technical aspects of how turbidity and NOM corrections are applied to raw sensor signals to ensure accurate nitrate measurements in water resources.
