A new Technical Sales Supplement (TSS #10) has been published to demonstrate the use of topographic measurements in conjunction with scanning electrochemical microscopy for sensor applications.
Application of the scanning electrochemical microscopy (SECM) technique to sensors or electrodes can provide invaluable information. Providing a high resolution view of the sensor’s activity or conductivity across the surface of the sensor can help the development of higher sensitivity sensors and sensors with greater reproducibility. Key to the measurement of electrochemical activity using the SECM technique is the ability to maintain in close proximity to the surface during a scan. The combination of the Optical-Surface Profiling (OSP) technique with the SECM allows a user to take a measure of the surface features and relieve the SECM probe’s position during the scan and effectively remove the effects of topology resulting in an artefact-free measure of the electrochemical activity.
The TSS entitled “OSP-SECM Height Relief. Application: Sensors & Electrodes” is available from Uniscan Instruments.
A new Technical Sales Supplement (TSS #09) has been published to demonstrate the use of topographic measurements in conjunction with scanning electrochemical microscopy for corrosion applications.
The importance of scanning electrochemical microscopy (SECM) to corrosion applications is of growing interest to both scientific and commercial sectors. SECM’s high resolution capabilities coupled with its quantitative analytical capabilities provide a novel method to interrogate and image a surface’s corrosion resistance. The combination of the Optical-Surface Profiling (OSP) technique with the SECM allows a user to take a measure of the surface features and relieve the SECM probe’s position during the scan. With the addition of Height-Tracking it is possible to effectively remove the effects of topology resulting in an unbiased measure of the electrochemical activity.
The TSS entitled “OSP-SECM Height Relief. Application: Corrosion” is available from Uniscan Instruments.
The RC10V is designed to automate the control of an electrode rotator and supports various models from major manufacturers.
The RC10V Rotator Controller accessory connects the BiStat 3200, PG580RM or PG580 potentiostat to an electrode rotator and remotely controls the rotational speed of the unit. The rotator speed can be set directly in software using the Rotator Velocity experiment included with the controller. The software experiment sequencer provides a versatile mechanism to implement complex automatic experiments. An example sequence supplied with the controller implements a completely automatic Levich experiment and analysis.
A brochure describing the product is available from Uniscan Instruments and their distributors.
A new Technical Sales Supplement (TSS #08) has been published to coincide with the introduction of the RC10V accessory from Uniscan Instruments.

Uniscan Instruments announces the introduction of the Scanning Droplet System, Model SDS370, to compliment its range of scanning probe instrumentation.
The scanning droplet technique 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 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 SDS370 is used in conjunction with the M370 x,y,z stage incorporating higher stability, flatness, measurement precision and all scanning axis benefit from highly accurate optical encoders providing precise closed loop feedback positioning over the full scan length. The SDS370 expands the range of scanning electrochemical techniques available from Uniscan Instruments for research and industrial applications and compliments the SVET, LEIS, SKP, SECM and OSP instruments already announced.
