The MultiTrace software controls the individual potentiostats of our multi-channel instruments and the individual working electrodes of polypotentiostats. MultiTrace is based on the PSTrace program for the PalmSens and EmStat instruments.

MultiTrace can control multi-channel potentiostats in two different modes:

1. Simultaneous mode

All potentiostats run the same measurement. The measured curves are displayed in a single plot and stored in a single data file.

2. Individual mode

All potentiostats are used independently. Measurements can be started on all channels with one click, or on each channel individually. Each measured curve is shown in its own plot. Data files can be stored in separate locations for each channel.
MultiTrace offers to open every single channel in a PSTrace window.
A full feature window for data analysis or other functions can be opened for each channel individually by double-clicking a preview plot.

A script can be run on each channel separately as well for running an automated sequence of tasks. See tab Scripting for more information.

The EmStat4WE polypotentiostat can only be operated in the Simultaneous mode, but as an alternative an individual constant potential can be applied to selected working electrodes.

Other functions in MultiTrace 4 are:

  • Equivalent Circuit Fitting
  • Scripting (on each channel)
  • Open your data in Origin and Excel with one click of a button
  • Save all available curves, measurement data and methods to a single file
  • Browse measurements on MultiPalmSens4’s internal storage
  • Dynamic feedback on method parameters

Combining multi- and single channel instruments

MultiTrace also allows you to combine different multi-channel or single-channel potentiostats.
Each single instrument can be assigned with a channel number and description. This allows you to extend your existing MultiPalmSens4 with a single-channel EmStat or PalmSens and let them work together as if they are one multi-channel device.


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)



In the Individual mode of MultiTrace you can create automated complex experiments for each separate channel.
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.
