A short and simple explanation

A multi-channel potentiostat allows you to perform multiple experiments at the same time.

Do you want to perform several electrochemical measurements simultaneously? Then you need a multi-channel potentiostat. A multi-channel potentiostat allows you to perform multiple experiments at the same time.

What is a multi-channel potentiostat used for?

Multi-channel potentiostats are mostly used in electrochemistry in complex experimental situations where many experiments are running in parallel, to be able to draw a conclusion from a certain experiment or research.

  • For example, you may need to perform multiple measurements with a long duration, e.g. charge-discharge curves for batteries.
  • Also, you may be quantifying multiple analytes with different sensors in a sample solution, e.g. water quality monitoring.
  • Finally, you may want to be able to examine multiple samples simultaneously so that you can make rapid progress, e.g. organic coatings on metal alloys for corrosion protection.

Applications for the use of multichannel potentiostats include combinatorial testing, coating analysis, microbial fuel cells, continuous corrosion monitoring, electrode array monitoring, sensor arrays and large-scale supercapacitor for battery evaluation. Feel free to check our literature database for more examples.

Which multi-channel potentiostats does PalmSens provide?

PalmSens has developed two multi-channel potentiostats which both have a galvanostat mode and are capable of FRA/EIS: the MultiPalmSens4 and the MultiEmstat4.

Our multi-channel instruments can controlled by our own MultiTrace software or by your own custom developed software program.

What differences are there between the MultiPalmSens4 and the MultiEmstat4?

Besides the similarities already mentioned, there are also some differences between our multichannel tools.

  • Our Flagship, the MultiPalmSens4 supports a higher potential range of 10 V and Electrochemical Impedance Spectroscopy (EIS) up to 1 MHz, whereas the MultiEmStat4 supports a potential range up to 6 V and for EIS frequencies up to 200 kHZ. The MultiEmStat4 High Range can handle up to 200 mA per channel, which is the highest current range PalmSens instruments offer.
  • An important difference is that the MultiPalmSens4 has an auxiliary port and a larger internal memory.
  • Finally, the MultiPalmSens4 is customized for you. You can have it completely configured to your own wishes. This can easily be done online on the product page. With the MultiEmStat4 you can also choose from a few simple product variations. However, the choice here is less extensive.

You can see all the other differences below in the comparison table:
