Floating ground for reliable EIS (electrochemical impedance spectroscopy) results

For materials development and condition testing of batteries, supercapacitors and fuel cells, state-of-the-art microelectronics combined with decades of experience in potentiostat design creates a powerful yet cost-effective measurement system. Whether you need to cycle your small batteries or polarize large electrode surfaces, the Interface instrument series provides either ± 5 A current at ± 6 V or ± 1 A current at ± 12 V at the working electrode. This series of instruments, like all other Gamry potentiostats, has a floating ground, so you can probe a grounded working electrode or multiple working electrodes in a common electrolyte for bipotentiostatic measurements, for example, or use it easily with other instruments such as AFM, QCM's and pH meters without fear of ground loops.
The multi-channel system of up to eight channels in the Interface Power Hub increases throughput, individual channels are removable and allow measurements on systems with short signal paths.
