Development of a plastic optical fiber oxygen optode with a fluorescence intensity measurement system

Abstract:

Environmental measurements are nowadays gaining momentum due to availability of open software/hardware solutions, which made them affordable to industry, academia, and technology enthusiasts. Air and water quality conditions are some environment related measurements that have several applications in ecology, industry and aquaculture. Here, an optical fiber probe or 'optode' for oxygen concentration measurement is presented. Due to its low cost and availability; plastic optical fibers with commercial Ru(II) oxygen patch were chosen to build a probe. Also, to extract information from the sensor a fluorescence intensity measurement system was employed due to its simplicity in implementation. To test this development, an experiment was made where 10 gaseous oxygen concentration levels were applied to obtain a calibration relation for the optode. It was demonstrated, due to the non-linearity of the sensor patch that a solubility model has good correlation to data instead of the usual linear relationship between intensity and oxygen concentration.
