with world-leading corrosion and materials analysis software
- offers complete AC/DC impedance, harmonic and electrochemical noise analysis
Solartron has extended its 'lab-in-a-box' series with the introduction of a complete electrochemical impedance analysis package at a highly aggressive price. Designed to fill the gap between specialist instruments and simple bench-top units, the new package offers top-end laboratory DC and AC impedance, harmonic analysis and electrochemical noise performance. Called 1280Z, this highly cost-effective package includes Solartron's proven 1280B plus the world's foremost corrosion and materials analysis software packages - CorrWare and ZPlot - bringing the full gamut of electrochemical experimental techniques within reach of most research laboratories, universities and quality departments.
Cornerstone of the package is Solartron's proven 1280B, combining the DC measurement capability of the company's de-facto industry standard 1287 potentiostat with a powerful frequency response analyzer (FRA).
DC analysis of multi-cell batteries is facilitated by the 1280B's unrivalled ±14.5V polarization and 2A current ranges, while the integrated FRA enables electrochemical impedance spectroscopy to be used to separate out individual cell reactions. The unit's ability to run stepped or smooth polarization sweeps, linear polarization scans and cyclic voltammetry, enables a range of corrosion/coatings analyses to be performed, while the built-in sweep freeze capability eliminates cell disturbance between tests. Ultra-stable measurements facilitate long-term trend analyses, such as studies into the performance of corrosion coatings and inhibitors, where resistance frequently exceeds 1 Gohm. 1280B is also ideal for electrochemical noise measurements, dual high accuracy 5-digit voltmeters providing true parallel voltage/current measurements with 1pA/1uV resolution.
AC impedance analysis is a highly versatile investigation technique, with applications in advanced materials R & D such as liquid crystals, ceramics, composites and piezoelectric devices, as well as battery research and corrosion analysis. The 1280B's tight integration of signal generation and response hardware ensures limits of error of less than 0.5% - the best available from any fully integrated electrochemistry instrument. When combined with the unit's linearity and flatness of frequency response, this maximizes the information available to the investigator.
Complete flexibility of interconnection is available with the instrument's 2-, 3- or 4-terminal measurement capabilities. All connections are fully floating, enabling the instrument to provide high resolution measurements both in the field, on grounded structures such as buildings, tanks and pipelines, and in the laboratory, when using such equipment as autoclaves which are grounded for safety reasons. Additionally, Solartron's 'driven shield' technology minimizes EMI and the unwanted effects of cable impedance.
Solartron's electrochemical impedance analysis applications software - CorrWare and Zplot/Zview - provides researchers with an extensive array of techniques with which to analyze the large volumes of data generated by electrochemical experiments. CorrWare, the de-facto standard for dc electrochemistry experiment management, integrates instrument set-up, data acquisition and results analysis through an easy-to-use graphical interface. Researchers can select from ten basic experimental set-ups, such as constant current or potential, swept current or potential, and cyclic voltammetry.
Zplot/Zview incorporates the latest advanced complex non-linear least-squares fitting algorithm [LEVM] to speed analysis of electrochemical impedance spectroscopy data in the investigation of material properties. Checking the goodness of fit of an equivalent circuit model is further simplified by the software's facility to view relative residuals, while a batch mode speeds the fitting of multiple data files to a single circuit.
