This enables the user to map and quantify localised electrochemical and corrosion events in real time.
The probe vibration is controlled by a piezo-ceramic displacement device allowing vibration amplitudes from 1 – 30 μm (perpendicular to the sample surface).
It is an ac technique, thus, high system sensitivity can be achieved via a differential electrometer in conjunction with a lock-in amplifier.
The SVP470 vibrating probe provides increased electrical sensitivity as well as enhanced system stability. The 3300 potentiostat is an option that offers a fully integrated suite of dc corrosion experiments and can be used to bias the potential of the sample.
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.
