Scanning Electrochemical Microscope

VS-SECM (DC And AC) - Ametek Scientific Instruments (Ametek SI)

The SECM integrates a positioning system, a bipotentiostat, and an ultramicroelectrode probe or tip. The positioning system moves the probe close to the surface of the sample, within the local imaging zone. The bipotentiostat can polarize the probe only (feedback mode) or the sample and the probe independently (generator-collector mode), while measuring the resulting current(s). The probe is specially designed to have a specific tapered polish (per the RG ratio) and active radius below 100 microns. The positioning system scans the probe and charts position with measured electrochemical parameters, creating a data map of local current.
