Abstract
The present invention provides a novel and unique device, method and system that detects thiocyanate in seawater with the halide ions present that can be provided in a hand-portable device that offers detection limits to 1-2 ppb which at least twice as sensitive as the nearest known device in the current state of the art. The sensor is also sensitive to nitrate ions (NO3−) in seawater at similar ppb concentrations as thiocyanate.
