This multiplexer allows the usage of a single PalmSens or EmStat Blue with up to 16 electrochemical cells, by switching between the different cells. A great way to raise efficiency.
A single PalmSens or EmStat Blue can be used to work with multiple working electrodes or a sensor array by means of a multiplexer. The multiplexer switches between their working electrodes in the range of milliseconds. There are two versions of the multiplexer available.
MUX8 multiplexer: enables to work with up to eight 2- or 3- electrode systems.
MUX16 multiplexer: enables to work with up to sixteen 2- electrode systems. The 16 working electrodes can have a shared counter and reference electrode, or each working electrode is matched with its own combined reference/counter electrode. If only the working electrodes are switching, one reference and one counter electrode shared by all working electrodes is a possible configuration.
