1. A system for analysing a fluid sample, the system comprising:
a carrier with a microfluidic channel for the fluid sample, the carrier being a microfluidic chip;
a socket for a plug, wherein the socket is arranged on the carrier and is open towards the channel;
the plug for plugging into the socket, the plug carrying a sensor and configured such that the sensor is in contact with an interior volume of the channel when the plug is plugged into the socket, wherein the sensor has an optical behaviour dependent on at least one variable of the sample;
wherein the sensor comprises one or more sensor elements, a sensor element being a patch of material containing a sensor substance, and wherein the sensor substance is a substance having the optical behaviour dependent on at least one variable of the sample.
