PSTrace for Corrosion Research

Easy and versatile

Dedicated modes make PSTrace easy to use. The Corrosion mode offers the corrosion techniques, analyze the results and perform equivalent circuit fitting with a few clicks.

Butler-Volmer and Tafel fit

The automatic Butler-Volmer or manual Tafel slope fit helps analyzing the results of Linear Polarization, to extract all the material properties.

One-click export to Excel

If you feel more comfortable using your own spreadsheets, use the one-click export to Excel. Or export your data to Origin or Matlab.

Corrosion mode

Provides a template for all the functions, to perform analysis on unknown samples or calibration of electrodes.

Corrosion mode

Convert your data quickly into physical properties. Corrosion mode comprises a straight forward modelling package with a dedicated tab to describe the physical properties of the material such as surface area.

EIS

Impedance

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.

Linear Polarization study made easy

Automatic Butler-Volmer or Tafel slope fit

Analyze the results of a Linear polarization to study the corrosion response of metallic coatings. PSTrace supports three analysis techniques to estimate the corrosion rate:

Auto Butler-Volmer fit: Fitting the Butler-Volmer model over an automatically detected range.
Manual Butler-Volmer fit: Fitting the Butler-Volmer model over a manually selected range.
Manual Tafel slope fit: Fitting Tafel slopes in the linear regions of the anodic and cathodic slopes.

Equivalent Circuit Fitting tool integrated in PSTrace

PSTrace comes standard with a 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 are 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

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.
