In this work we present the gas sensing properties of rare-earth doped nanoparticular metal oxides which have been prepared by the polyol mediated synthesis. The materials are studied using a high-throughput equipment, applying multi electrode substrates and high-throughput impedance spectroscopy in a temperature range from 500 to 200°C and under various gas atmospheres (synthetic air, H₂, CO, NO, NO₂, ethanol and propylene). We will report about the development of this new experimental technique and its potential to be applied for gas sensor development.
