Abstract
A fiber optic ammonia gas sensing probe is described In which the pH indicator dye p-nitrophenol is employed to detect pH changes of an internal electrolyte solution. The resulting pH change is measured as light absorbance and is related to the sample ammonia concentration. Ammonia measurements in aqueous solutions are demonstrated with a lower limit of detection of 5 μM. An equation Is derived from fundamental concepts to simulate the response of this fiber optic ammonia sensor.
