Model 1280C Potentiostat/Galvanostat with built-in FRA

Model 1280 Potentiostat with built-in FRA

The  Model 1280Z Electrochemical Test System offers a high accuracy, wide bandwidth potentiostat / galvanostat and a frequency response analyzer (FRA) in a single compact unit.

Measurement Integrity
Central to the measurement capability of 1280Z are two high resolution digital voltmeters which provide simultaneous voltage and current measurements. Using Solartron’s patented pulse width conversion technique, they have high accuracy, stability and linearity throughout the entire range of the instrument.

The 1280Z has excellent measurement resolution and accuracy down to 1μV for the reference electrodes and 1pA
for the working electrode, which makes it an ideal choice for measurements where signal levels are extremely low.
The 1280Z uses floating measurements on all connections: it is equally at home measuring corrosion rates on grounded oil pipelines as it is in the laboratory. For safety reasons, it is often necessary to ground laboratory
equipment such as autoclaves, a major problem if your instrumentation is not capable of floating measurements.

The 1280Z offers complete flexibility for cell connection: 2-, 3- or 4-terminal measurements can be made
with equal ease.

  • 2-terminal techniques for general materials / electrochemical testing
  • 3-terminal techniques for corrosion / coating applications
  • 4-terminal techniques for accurate characterization of batteries and fuel cells, enabling lead resistance and impedance effects to be minimized

Applications
The 1280Z is used in numerous electrochemical and materials based research and development fields including:

  • Corrosion and inhibitor studies
  • Sensor research
  • Battery / fuel cell development
  • Electrosynthesis / electrodisposition
  • Civil engineering, concrete / metals
  • Dielectric materials, LCDs / ceramics / polymers
  • Bioanalytical research, plants / soils Impedance

Electrochemical Impedance Spectroscopy (EIS) is widely used to enhance the information about reaction
mechanisms available from DC techniques. 1280Z was designed to carry out both DC and impedance (AC)
tests, providing a complete measurement solution. Solartron FRAs use a single sine correlation algorithm which offers
excellent noise and harmonic rejection. The technique is particularly powerful for electrochemical applications since
signal levels are usually very low (of the order of millivolts), and are inevitably buried in noise. With the 1280Z it is possible to characterize cells over a wide range of impedance.

When making high frequency impedance measurements, Solartron’s driven shield technology minimizes the unwanted effects of cable impedance enabling 1280Z to be used over a 1mHz to 20kHz frequency range.

Electrochemistry Software
CorrWare and ZPlot packages are specifically designed to run a wide range of electrochemical tests including:

  •  Impedance
  •  Step / pulse techniques
  •  Cyclic voltammetry

CorrWare and ZPlot are an ideal tool for corrosion analysis, battery / fuel cell research, and general electrochemistry. The software provides, real-time analysis, multiple display formats and curve fitting routines.
