Multi-channel Potentiostat / Galvanostat / Impedance Analyzer
- 4 to 10 channels available in different configurations
- FRA / EIS: 10 μHz up to 1 MHz
- 9 current ranges: 100 pA to 10 mA
- potential range: ±5 V or ±10 V
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
- Galvanic isolation
Always a backupEvery 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.

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.
MultiTrace for Windows
The MultiTrace software gives you full control over the channels of our multi-channel instruments. MultiTrace can be used with multi-channel potentiostats in two different modes; the Individual and Simultaneous mode.
All potentiostats are used independently. Measurements can be started on all channels with one click, or one at a time on individual channels. Each measured curve is shown in its own plot.
All channels run the same measurement at the same time (optionally hardware-synchronized). The measured curves are displayed in a single plot and can be stored together in a single data file or in separate data files.
Software Development Kits
The PalmSens Software Development Kits (SDKs) for .NET can be used with any of our instruments or OEM potentiostat modules to develop your own software. The SDK’s come with a set of examples that shows how to use the libraries.
PalmSens SDKs with examples are available for the following .NET Frameworks:
- Xamarin (for Android)
