Analysis device and method for testing the catalytic activity of surfaces

A method for studying the catalytic activity of surfaces by using an analysis device, the method comprising the steps of:

• fitting a sample provided with the catalytically active surface into a compartment of a reactor cell, and
• optically studying the reactions taking place in the reactor cell by a measuring arrangement,
• wherein
• the reactor cell consists of a closed channel which forms part of a fluidic circuit, a fluid containing educts of a reaction to be catalytically studied being circulated in the circuit, and
• a measurement beam is generated by a light source in the measuring arrangement, the measurement beam is introduced into the channel, the measurement beam is reflected at least once by the wall of the channel, the measurement beam emerges from the channel and the measurement beam strikes a light sensor.
