Abstract

To monitor functions in a micro-fluidic system having mutually similar parallel fluid paths, sensors (7) are assigned to the individual fluid paths (5) at the same respective locations, in order to measure a physical parameter that is influenced by the fluid stream in the fluid paths (5). The sensors (7) are connected to an evaluation device (10), which diagnoses a change in the operating state of the micro-fluidic system based on the differences in the parameters measured by the sensors (7).
