Optochemical oxygen sensor

The measuring principle of the optochemical oxygen sensor is based on the effect of dynamic luminescence quenching by molecular oxygen. When the light falls on the luminescent layer, it excites the atoms; excited atoms return to their ground state (which is energetically favorable for them), "throwing out" excess of energy, so-called luminescent light, which can be detected. However, if there are molecules of oxygen on the way to the detector, the fluorescent light will be partially absorbed by them, and this will be fixed by the detectors. The phenomenon when oxygen takes energy from an excited luminophor is called "dynamic luminescence quenching." The article contains a detailed description of this phenomenon, about measured values and units, as well as the information about main advantages of this method, and about the measuring principle of the optochemical oxygen sensorand its design .
Application: the oxygen sensor is used in the pharmaceutical industry, medical research and in the beverage industry.
