Abstract
A sensor for measuring an oxygen content in a liquid or gaseous sample has first and second sensor sections (). The first sensor section () 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 () is arranged adjacent to the first sensor section () and includes the same dye embedded in an oxygen-impermeable second polymer matrix. A light guide () guides luminescence excitation light from a light source () to the sensor sections () and guides luminescence emission light from the sensor section () to a detector ().
