Abstract
A sensor element has a channel into which a sensor substance can be fed from a reservoir of the sensor element. The sensor substance has an optical behaviour which depends on an analyte. The analyte passes from a sample through a membrane permeable to the analyte into the channel, which membrane forms a portion of a wall of the channel.
Claims17
A sensor element comprising:
- a reservoir comprising a sensor substance having an optical behaviour depending on an analyte;
- a channel, wherein the sensor element is configured such that the sensor substance can be fed from the reservoir into the channel;
- and
- a membrane which is permeable to the analyte and which forms a portion of a wall of the channel.
