1280B Electrochemical Workstation
The powerful combination of FRA and ECI in a single, compact unit is equally at home on the bench or on the field. When used with ZPlot for Windows, it offers a complete range of EIS techniques, including AC impedance and harmonic analysis. The use of CorrWare with the 1280B allows all standard DC electroanalytical analysis techniques to be programmed, including electrochemical noise.
Features
Full floating measurement capability for grounded cells, autoclaves, storage tanks and pipelines
- 1pA / 1µV resolution
- ±14.5V, ±2A polarization
- 1mHz to 20KHz frequency range
From materials screening in the laboratory to on-site corrosion monitoring the Solartron 1280B has the power to perform:
DC polarization
The simplest of all electrochemical techniques - a controlled ramp voltage is applied to the sample and the change in current plotted.
Harmonic Analysis
A common application of this technique is to calculate corrosion rate from the measurement of harmonic data.
Electrochemical Noise
Random current and voltage fluctuations are recorded over time without applying an external stimulus. To achieve meaningful results, voltage and current must be measured simultaneously. This technique is entirely passive and therefore requires highly sensitive and accurate instrumentation; ideal for the 1280B.
Impedance
Electrochemical impedance spectroscopy (EIS) is a flexible and sensitive technique which can be used to gain detailed insights into the physical and chemical properties of a sample. When a variable (AC) voltage is applied the ratio to the measured current is called the impedance. This impedance varies according to the frequency of the voltage. Measured across a broad frequency range the results plotted in Bode or Complex plane formats reveal information undetectable using other methods of investigation.
Applications
An innovative and inherently non-destructive technique, EIS is already being used in research and development work in the following areas:
- Corrosion studies
- Battery research and fuel cells
- Solar cells
- LCDs
- Bio-materials
- Dental research
- Electronic component development
- Civil engineering
- Dielectric measurements
- Semiconductors
- Coatings research
