Eco Chemie Autolab Potentiostats

General electrochemical software

Whether it is a simple CV measurement or a complex series of analyses, measurements and control commands, the GPES software package provides you with an easy-to-operate interface for total system control.

The Autolab GPES software package provides you with almost all the electrochemical techniques required for your research. You simply have to choose the methods you want to use in the “Edit procedure” window, then define the parameters and start the experiments. The measurement procedures can be stored separately from the data and reloaded later to perform measurements under standardized conditions. Below an overview of the available methods is given:

Electroanalytical methods include:

• Sampled DC-voltammetry
• Normal pulse, differential pulse and differential normal pulse voltammetry
• Square wave voltammetry, with frequencies from 8 to 2,000 Hz
• AC-voltammetry, with frequencies from 1 to 250 Hz, as well as the possibility to measure the second harmonic

Cyclic and linear sweep voltammetry:

• Staircase potentiostatic and galvanostatic voltammetry
• True linear sweep voltammetry (with SCAN-GEN only)
• Stationary current voltammetry
• Current integration method
• Bi-potentiostatic measurements
• Hydrodynamic linear sweep voltammetry
• Possibility to measure with respect to the open circuit potential

Chrono methods:

• Chrono-amperometry
• Chrono-coulometry
• Chrono-potentiometry

Other options include:

• Steps and sweeps techniques allow you to create your own techniques
• Setting of current, potential or charge limits for the protection of electrodes and cells
• Maximum of 10 potential or current levels
• Automatic data storage
• Automated recording of extra data points with large changes in the response
• Bi-potentiostatic measurements
• Measurements at or with respect to the open circuit potential

Project manager and wizard

The Autolab software provides you with a powerful “Project mode” for programming a sequence of events to automate a complex series of analyses measurement and control steps, including impedance measurements into one experiment.

With the easy-to-use “Project wizard,” you can set up a complex experiment that simply involves the uploading of experimental parameters, starting the experiment, saving the data and repeating the whole sequence.

Data analysis

You can perform data analysis on measured and/or stored data in the “Data presentation” window. The list below gives a short overview of available data analysis options:

• Automatic or interactive peak search
• Linear, exponential and polynomial baseline correction
• Linear regression
• Smoothing: FFT and weighted moving average
• Integration and differentiation
• Convolution and deconvolution
• Fitting and simulation of voltammograms
• Blank subtraction
• Data set comparison
• Kinetic and wave log analysis for s-shaped voltammograms
• Automatic corrosion rate and polarization resistance determination
• Report generation with graphics
• Levich plots
• Transient time analysis for chrono-potentiometry
• Chrono-coulometric and chrono-amperometric plots
• Coulometric titration plot
• Fourier transformation
• And much more
