Abstract

A sensor for measuring an oxygen content in a liquid or gaseous sample has first and second sensor sections (14a, 14b). The first sensor section (14a) can be brought into contact with the sample and has a luminescent indicator dye embedded in an oxygen-permeable first polymer matrix. The second sensor section (14b) is arranged adjacent to the first sensor section (14a) and includes the same dye embedded in an oxygen-impermeable second polymer matrix. A light guide (10) guides luminescence excitation light from a light source (31, 32) to the sensor sections (14a, 14b) and guides luminescence emission light from the sensor section (14a, 14b) to a detector (39).
