摘要：

A mathematical model is derived from the Stern-Volmer equation as a practical calibration function for various optical oxygen sensors based on quenching of ruthenium fluorescence. The model is simple and flexible, and is ideal for computing oxygen partial pressure from 0 to 760 Torr in gaseous samples, and 0 to 200 Torr in aqueous samples. Feasibility of this model for dissolved oxygen calibration is demonstrated by applying the model to data acquired from a set of three radioluminescence-based optical oxygen sensors. The model is applicable to various sensor designs and adequately accounts for stray radiation and other sources of non-quenchable light. (C) 1998 Elsevier Science B.V.
