Abstract:
1. An analysis device for studying the catalytic activity of surfaces, comprising a reactor cell comprising a wall having an installation opening receiving a compartment for a sample provided with the catalytically active surface, and a measuring arrangement for optically studying the reactions taking place in the reactor cell arranged on the reaction cell opposite said installation opening, wherein the reactor cell consists of a closed channel which forms part of a fluidic circuit, wherein predictable reaction conditions avoiding local saturation effects are provided by an integration of the reaction cell into the channel of the fluidic circuit, wherein when said compartment is inserted into the installation opening, the catalytically active surface forms a part of the channel wall, and the measurement arrangement comprises a light source for generating a measurement beam and a light sensor for this measurement beam, the measuring arrangement allowing the measurement beam to be introduced into the channel and allowing the measurement beam to emerge from the channel in such a way that the measurement beam is reflected at least once by the catalytically active surface.
