PSTrace software is shipped as standard with the PalmSens, Emstat and EmstatMUX instruments. The software provides support for all techniques and device functionalities. With a smooth simple interface, showing only the applicable controls, PSTrace is suitable for all levels of user experience.

Setting up your measurement

The method editor provides instant feedback on parameters that are either invalid or do not match the instruments capabilities:

Measurement data

All measurement data and curves are stored in a single .pssession file. Peaks are detected automatically or can be marked by hand. Exporting data to Excel including generation of a native Excel graph is a matter of a single click.

Dedicated modes as Corrosion and Analytical Mode exist, offering extensive help files and prompts are to guide the user through a typical analysis.

Making it easy for simple measurements doesn’t mean we compromised on advanced electrochemistry. To create a complex series of experiments a scripting window is used. Scripting enables automated and batch analysis with full control over data manipulations and output, providing automation of all of the main functions of PSTrace. The interactive plot and a ‘head-up-display’ of peaks when hovering over the peak location made also the post-measurement part of electrochemistry just quicker and easier. But if you feel more comfortable by using your own spread sheets, you can use the one-click export to Excel. Or you can export your data to Origin or Matlab.

Minimum system requirements

  • Windows Vista, 7, 8, or 10 (32-bit or 64-bit)
  • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
  • 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)



Three discrete modes are used to streamline your work by focusing only on the relevant electrochemical and hardware components

Scientific mode

In this standard mode all methods and functions are available, while still maintaining a clean interface. Also peripherals such as a magnetic stirrer are all controlled automatically making them ideal for stripping analysis such as Anodic Stripping Voltammetry or Cathodic Stripping Voltammetry. This is the most used mode, since it offers the full range of electrochemical methods and complete control over each single parameter.


Analytical mode

This mode provides a template for all the functions to perform analysis on unknown samples or calibration of electrodes. Quantitative analysis according to the standard addition method or a calibration curve is performed in a few easy steps. Even multiple analytes are possible. The results window then provides the platform to complete the analysis, calculate the results and statistical variations of them. The Analytical mode is perfect for everyone, who wants to save time during their quantitative analysis.

Corrosion mode

This mode is made to convert your data quickly into physical properties. It comprises a straight forward modelling package with a dedicated tab to describe the physical properties of the material such as surface area. This mode supports using the techniques, CV, LSV, AD and Potentiometry/OCP. Interacting with the plot and results is focused to corrosion analysis, so Tafel Plots and the common corrosion modelling functions such as the Stern-Geary equation are done with a few clicks.



PStrace provides different options for analysis and simulation of impedance spectra.

Equivalent Circuit Fitting tool integrated in PSTrace

PSTrace comes standard with a new tool window for Equivalent Circuit Fitting. Drawing your circuit and fitting your data has never been easier. The interface allows you to quickly draw or change the circuit design. The circuit and fitted data is automatically saved with your .pssession data file.

The circuit editor can be used in different modes;

  • Edit mode; draw the circuit or type CDC circuit
  • Fit mode; fit the EIS data on the circuit
  • Simulation mode; run simulations on circuits



PSTrace has integrated export functions for ZView™ from Scribner Associates. ZView is a popular program for equivalent circuit modeling and data analysis. This integration allows you to export measured data from PSTrace to ZView with one click of a button. The most recent circuit diagram used remains active for each new impedance curve exported to ZView.



You can create automated complex experiments with this highly versatile component rich control for automated and batch analysis. In the scripting window you can easily arrange your building blocks for automated saving, blank subtraction, peripheral control, peak data saving and many more to create your own method. Automatization of all your methods leads to more stable results and frees up user time for other tasks. Complex electrochemical procedures such as pseudo polarography can be simplified with higher functions such as deposition potential override.
