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.
* Not supported for on-device backup: EIS, MultiStep and MixedMode

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.

Software

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.

Individual 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.

Simultaneous mode

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:

  • WinForms
  • WPF
  • Xamarin (for Android)
