Experiment Research of PtOEP Oxygen Sensor
Abstract: An oxygen sensor is designed using a fluorescent substance PtOEP (platinum-octaethyl-porphyrin) as an indicator, based on the principle of fluorescence quenching. Design idea is that: first, square wave modulation for LED excitation light source is made; second, the light irradiates in PMMA (Polymethyl Methacrylate) with fluorescent indicator, which produces fluorescence excitation and then fluorescence intensity also shows square wave change; Last the relationship between the oxygen concentration and fluorescence intensity is calibrated using gas mixer. The sensor has high precision, good stability and repeatability, and has faster response speed. The sensor can be used to measure the unknown environment (such as animal cell culture environment) of oxygen con-centration.
