Abstract

Sensing, monitoring, and controlling the concentration of oxygen is vital in biological, medical, environmental applications, Numerous scientific and industrial applications demand the knowledge of partial pressure of oxygen. The present industrial standard oxygen sensor is a modified polarographic Clark-electrode. This sensor suffers from many limitations.1 Optical sensing of oxygen offers an attractive alternative and we present here, an oxygen sensor based on the principle of phase modulation fluorimetry.2
