Emstat MUX & CH8 Multiplexers

Description:

This is an integrated unit containing either a CH8, 8-way of a  or MUX.

CH8 multiplexer

The CH8 multiplexer connects up to eight electrochemical cells or sensors to the EmStat potentiostat. Possible configurations are:

1. Eight separate cells or sensors each with a working, reference and counter electrode
2. Eight separate cells or sensors each with a working and combined reference and counter electrode
3. Cell or sensor array with eight working electrodes sharing a reference and a counter electrode
4. Cell or sensor array with eight working electrodes sharing a combined reference/counter electrode.

In all configurations the sensors can be multiplexed, leaving unselected electrodes or sensors at open circuit. In configurations 2, 3 and 4 the specified potential may be applied to all electrodes simultaneously.

Mux multiplexer

This connects up to sixteen working electrodes to the EmStat potentiostat. Possible configurations are:

1. Sixteen separate cells or sensors each with a working and combined reference and counter electrode
2. Cell or sensor array with sixteen working electrodes sharing a reference and a counter electrode
3. Cell or sensor array with sixteen working electrodes all sharing one combined reference/counter electrode.

In all configurations the sensors can be multiplexed, leaving unselected electrodes or sensors at open circuit, and the working electrodes can be multiplexed, leaving the unselected electrodes at open circuit, or with the potential applied to all working electrodes continuously.

Both multiplexers are supported by PSTrace software, and both enable sequential channel selection and measurements. In amperometric mode all 8 or 16 channels can be measured simultaneously, yielding up to sixteen curves in a single measurement.
