Multichannel Potentiostat/Galvanostat topologies

There is a multitude of scenarios that demand more than one channel of a potentio-/galvanostat. The reasons vary greatly – just to name a few typical settings:
- automating sequential multi-sensor probing over
- the need of scaling up experiments to more throughput via parallel experiments
- complex multi-electrode arrangements with need for specific synchronized control
- simultaneous comparison of a single or a set of test targets/sensors to a single or a group of reference sensors
As diverse as the reasons for using multichannel arrangements are the choices for solutions. In general, there are four basic approaches:
- multiple single-channel potentiostat / galvanostat
- multiplexing
- multi-potentio-/galvanostat
- poly-potentiostat
