External EIS Module for Micro-EIS Matrix Mapping
The external EIS module supports electrochemical impedance measurements for both macro-sized and micron-scale substrates. EIS mapping in 2D line scan, 3D Matrix scan (protocol-controlled) can be performed. A frequency spectrum scan at fixed local positions is available with results displayed in Bode and Nyquist plots. Micro-EIS Matrix Mapping, with micron and sub-micron spatial resolution, are implemented in SECCM mode, which is capable of imaging surface’s local impedance and topography height simultaneously. The EIS module includes the main External EIS Unit, HEKA’s SECCM-EIS working electrodes for micro-EIS measurements, as well as a Model Cell and all connection cables to be used within an ElProScan system.
