Design Specifications

The device sensing region uses L-glutathione (GSH), a chelating agent which functions to specifically bind Pb2+ onto the optical fiber sensor for on-site detection of heavy metal ions. The detection time is less than five minutes, and can detect up to 24 metal contaminants. The device has an overall dimension of 203 mm × 149.50 mm × 65 mm and weighs 0.8 kg.
