High Throughput Experimentation (HTE)
The HTE@ETH lab has two liquid handling robotic platforms to prepare catalyst formulations and test them at elevated temperatures and pressures under strictly anaerobic conditions. Up to 96 experiments can be carried out simultaneously on both heterogeneous and homogeneous catalysts and a gas-uptake parallel reactor operated inside a glovebox allows for the reaction optimization studies and mechanistic investigations.
