Ability to spatially resolve electrochemical activity.
The Scanning Droplet System incorporates a technique which confines a liquid in contact with a sample surface in order to measure electrochemical and corrosion reactions over a limited region where the droplet is actually in contact with the sample. This offers the ability to spatially resolve electrochemical activity and to confine it exclusively to a quantifiable area of the sample. The scanning droplet system allows a spatially resolved, in-situ investigation by the standard electrochemical techniques such as line scans, area maps, potentiostatic pulse steps and open circuit measurements. The electrolyte flow through the cell is controlled via a precision peristaltic pump thus ensuring a good reproducibility of the free droplet wetted area.
