Eighty isolated channels are present in the array microreactor system that was coupled to a quadrupole mass spectrometer for high‐throughput testing of heterogeneous catalyst libraries. The system was used to monitor the activities, selectivities, and reaction kinetics of 66 ternary Pt/Pd/In catalysts for the dehydrogenation of cyclohexane to benzene over 24 h. It was possible to screen the entire 80‐channel library in less than 10 minutes (see picture).
