The S423/C/OPT probe is used for the optical measure of oxygen in pure and process waters. The principle of measurement is based on the effect of dynamic luminescence quenching by molecular oxygen. The collision between the luminophore in its excited state and the quencher (oxygen) results in radiationless deactivation and is called collisional or dynamic quenching. After collision, energy transfer takes place from the excited indicator molecule to oxygen which consequently is transferred from its ground state (triplet state) to its excited singlet state. As a result, the indicator molecule does not emit luminescence and the measurable luminescence signal decreases. A relation exists between the oxygen concentration in the sample and the luminescence intensity as well as the luminescence lifetime which is described in the Stern-Volmer-equation.


Applications:
• Measure of oxygen in wastewater
• Measure of oxygen in primary, industrial, recirculating water
