EmStat MUX: interface for sensorarrays
EmStat boards can be extended with the MUX8 or the MUX16 multiplexer. The EmStat with Multiplexer or EmStat MUX comes in a very compact housing.
The EmStat MUX8 multiplexer provides users to connect up to eight electrochemical cells or sensors to the EmStat potentiostat. This multiplexer can be used with different electrode or sensor configurations:
- Eight separate cell or sensors each with a working, reference and counter electrode,
- Eight separate cell or sensors each with a working and combined reference and counter electrode,
- Cell or sensor array with eight working electrodes sharing a reference and a counter electrode,
- Cell or sensor array with eight working electrodes sharing a combined reference/counter electrode.
In all configurations the sensors can be multiplexed, leaving the not-selected electrodes or sensors at open circuit.
Configurations 2, 3 and 4 also have the possibility to apply the specified potential to all electrodes or sensors continuously.
The MUX16 multiplexer provides users to connect up to sixteen working electrodes to the EmStat potentiostat. This multiplexer can be used with different electrode or sensor configurations:
- Sixteen separate cells or sensors each with a working and combined reference and counter electrode,
- Cell or sensor array with sixteen working electrodes sharing one reference and one counter electrode,
- Cell or sensor array with sixteen working electrodes all sharing one combined reference/counter electrode.
In all configurations the working electrodes can be multiplexed, leaving the not-selected electrodes at open circuit, or having the potential applied to all working electrodes continuously.
Both multiplexers are supported by the PSTrace software and provides the possibility to select a channel and to start a measurement using the selected channel or measuring all channels consecutively.
In amperometric mode all 8 or 16 channels can be measured simultaneously, yielding up to sixteen curves in a single measurement.
