Description
The MultiPalmSens4 is a flexible multi-channel potentiostat, galvanostat and impedance analyzer which you can fully tailor to your requirements and budget. The MultiTrace software allows for using each channel individually or simultaneously or running a sequence of automated tasks on each channel. Each channel provides an additional auxiliary port for controlling peripherals or monitoring temperature or other analog signals.
Configure your ideal multi-channel potentiostat
Each channel can be configured with:
- ±5 V or ±10 V maximum potential range
- EIS/FRA with maximum frequency of 100 kHz or 1 MHz
- Bipotentiostat module for second WE
- iR-Compensation
- Galvanic isolation
Always a backup
Every channel of the MultiPalmSens4 is equipped with 8 GB storage space. This means all your measurements* can automatically be saved on-board as backup.Measurements can be browsed and transferred to the PC easily using the MultiTrace software for Windows.
Synchronizing channels in Synched mode
By enabling synchronization of channels and adjusting the setup of your cables, you can use the MultiPalmSens4 as a polypotentiostat. This means you can use multiple working electrodes, one counter and one reference electrode in the same cell at the same time. Your working electrodes all perform the same measurement.

Electrochemical Impedance Spectroscopy (EIS) is an electrochemical techniques to measure the impedance of a system in dependence of the AC potentials frequency. With this option you can select the maximum AC frequency for EIS.
BiPot stands for BiPotentiostat, which is a potentiostat with two working electrodes. A bipotentiostat can use two working electrodes, one reference and one counter in the same cell. The two working electrodes can be operated and monitored exactly at the same time. Working electrode 1 performs any of the supported techniques (see below), while working electrode 2 can either have its own constant potential or follow the working electrode 1’s potential. In the latter case a potential offset can be added.
The resistance between the reference electrode and the double layer of the specimen can cause a significant potential drop, decreasing the applied potential where it is required. The module provides positive feedback to compensate for the IR drop between the Reference electrode and the outside of the double layer of the electrochemical cell.

Software
MultiTrace for Windows
The MultiPalmSens4 comes with MultiTrace for Windows. MultiTrace allows the instrument to be controlled in two different modes: Individual and Simultaneous channel control mode.
Individual mode
The individual mode gives an overview of all channels. Each channel can be selected separately and can run a measurement independently in parallel with other channels. You can also run a script for a sequence of measurements and other actions on each channel.
Simultaneous mode
In the Simultaneous Mode the MultiPalmSens4 works with all channels running the same measurement in parallel at the same time. There is only one active method in the Method Editor which is started on all selected channels simultaneously upon start. All results are presented as overlays in the same plot.
Software Development Kits
PalmSens provides several Software Development Kits (SDKs) to help developers create custom software to control their potentiostat. Each SDK comes with documentation and examples that shows how to use the libraries.
SDKs are available for:
- .NET (WinForms, WPF and Xamarin for Android)
- Python
- LabVIEW
- Matlab
