Abstract: A ratiometric method for using optical sensors (11) is provided to measure dissolved oxygen in a fluid sample. The sensor (11) is formulated so as to contain an oxygen permeable membrane (16) of a cured perfluorinated urethane polymer and, incorporated therein, an oxygen-sensitive indicator component and a reference dye component. The emission spectrum from the indicator component is calibrated by comparison with that of the reference dye, which is substantially less sensitive to oxygen-quenching and which has a photodecomposition rate similar to the indicator component. Methods for making and using the membrane and sensor (11) are provided as well.

Abstract translation: 提供了使用光学传感器（11）的比例计方法来测量流体样品中的溶解氧。 将传感器（11）配制为包含固化的全氟化氨基甲酸酯聚合物的透氧膜（16），并且其中并入氧敏指示剂组分和参考染料组分。 通过与参考染料的比较来校准来自指示剂组分的发射光谱，其对氧气淬灭基本上较不敏感，并且具有与指示剂组分相似的光分解速率。 还提供了制造和使用膜和传感器（11）的方法。
