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 SDS370 uses a precision peristaltic pump to deliver precise amounts of
electrolyte to the sample surface. The technique as quoted in the scientific
literature employs a glass theta capillary to deliver the drop to the surface
but Uniscan have engineered a more robust design from PTFE without sacrificing
any functionality. The counter and reference electrode are contained within the
PTFE capillary block.
Uniscan Instruments are the first to market with a commercial product but the
technique has been used for fundamental research in laboratories around the
world.
Application areas:
Characterization of surface oxides
Investigation of coatings
Characterization of ISFETs
Investigation of pitting corrosion
Localised corrosion versus flow rate
