Amount of instruments installed

Surfaces & Interfaces owns a total of three 1287s, four 1286s, four 1255s and two 1250s. Together, these allow six impedance setups to be built. In addition to these instruments, two Autolab PGSTAT 30s are available for EIS measurements as well.

Additional information

All EIS setups are galvanically isolated from their controlling PCs to maintain clean signals. This is performed by connecting the PC through National Instruments GPIB-120A bus isolators. Faraday cages are used to shield EM radiation from the experiment. Clean measurement earthing terminals are available throughout the lab.

All EIS setups are controlled using Scribner Associates Corrware & ZPlot software.
