Press Release Summary:
LEIS270 Localized Electrochemical Impedance Spectroscopy system, combined with existing electrochemical impedance measurement system provides capability to obtain spatially resolved voltage and current-based impedance data. Precise placement of scanning probe is achieved via optical encoders on all 3 axes. Single frequency scan of sample allows for mapping of impedance values in 2-dimensional format.
Original Press Release:
Princeton Applied Research Announces an Addition to the Surface Imaging Product Line, the LEIS270
Oak Ridge, TN - Princeton Applied Research has announced the introduction of the LEIS270 Localized Electrochemical Impedance Spectroscopy system. The LEIS270, combined with an existing electrochemical impedance (EIS) measurement system (such as a potentiostat and lock-in amplifier or frequency response analyzer) provides the enhanced capability to obtain spatially resolved voltage or current-based impedance data rather than the surface averaged or bulk impedance results obtained with conventional EIS measurement techniques.
Precise and accurate placement of the scanning probe is achieved via optical encoders on all 3 axes, with a minimum step size resolution of 1 micron. The maximum scan range is 70 mm in both x and y axes, and the ergonomically designed triaxial translation scanning stage and sample holder provides unmatched versatility and accessibility for accommodating various sample geometries and sizes. A single frequency scan of a sample allows for the mapping of impedance values in a 2-dimensional format, making identification of a feature or area of interest clearly visible. Intelligent point and click Windows(TM) based software allows for the movement of the scanning probe to any point chosen on the sample surface for a multiple frequency EIS measurement of a specific feature. This allows researchers to accurately map impedance measurements for the evaluation of localized corrosion, coatings performance and delamination, inhibitor and surface oxide studies, etc.
