The LEIS470 allows spatially resolved impedance measurements to be made, combining established principles of EIS measurements with BioLogic’s unique Model 470 scanning probe technology and has been designed to provide a totally integrated spatially resolved measurement system.
The principles of LEIS are similar to those employed in traditional bulk EIS, in that a small sinusoidal voltage perturbation is applied to a working electrode sample and the resulting current is measured to allow the calculation of the impedance. However, rather than measure the bulk current, a small electrochemical probe is scanned close to the surface, measuring the local current in the electrolyte.
Producing area maps over a sample at a single frequency has never been easier. The LEIS470 also allows the user to make galvanic or bulk impedance measurements simply by choosing which mode the potentiostat is operating in, and the software does the rest.
M470 is available with a choice of potentiostat/galvanostat/FRAs: in place of the 3300, which is built-in the M470, the SP-300 can now be used with the M470.
