Abstract

The study of fiber optic sensors for real time measurements is one of the fastest growing areas in analytical chemistry. With potential applications in biotechnology, blood chemistry, biofermentor control and anaerobic process control, measurement of gases has become increasingly important. In particular, oxygen has created a great deal of enthusiasm due to its biological importance and the number of biochemical reactions either using oxygen as a reactant or releasing it as a product. Currently, the most widely used method to determine oxygen concentration is the electrochemical sensor based on the Clark electrode.
