Abstract:

Oxygen sensors are used extensively in various fields to determine the oxygen concentration. Amperometric determination of molecular oxygen in water using Clark-type electrodes is widespread, but recent advances in fiber optic technology, light sources and detectors have boosted the development of oxygen sensors based on fluorescence quenching of suitable indicators by oxygen[1,2]. In situ, reversible, electrical-free, highly sensitive, specific measurements can be performed in real time using on-line fiber optic monitors, with a potential bonus of increased resistance toward chemical and biological attack.
