Hardware for Scanning Electrochemical Microscopy (SECM)

Below is a list of our key publikations, in which important hardware developments are documented for scanning electrochemical microscopy (SECM).

SECM Measurement Head for Gas Diffusion Electrodes

The gas diffusioin electrode is mounted between two gas reservoirs. The upper reservoir contains an inert gas, the electrolyte cell and the microelectrode. The lower comaprtment contains a gass mixture with a well dajustable oxygen partial pressure. Oxygen diffuses through the gas diffusion electrode into the electrolyte solution and can be converted there. The microelectrode is used to detect with high time resolution either oxygen or the reaction products formed upon oxygen reduction.
