AB  - A portable instrument for oxygen determination, based on the quenching of 
      phosphorescent octaethylporphyrin by gaseous O(2), has been developed using the 
      fluorimetric paired emitter-detector diode technique (FPEDD). The instrument 
      configuration consists of two light-emitting diodes (LEDs) facing each other, 
      with an interchangeable support containing a phosphorescent membrane in between, 
      in which one of the LEDs is used as the light source (emitter LED) and the other, 
      working in reverse bias mode, as the light detector. The feasibility of using a 
      LED as a luminescence detector is studied. Its small size enables integration of 
      the instrument into a portable measurement system. A systematic study of the 
      system capabilities as a portable instrument was performed to optimize range, 
      sensitivity, short term and long term stability, dynamic behaviour, effect of 
      temperature and humidity, and temporal drift.
