Gamry IMX8 (8-channel electrochemical multiplexer)
Gamry IMX8 (8-channel electrochemical multiplexer)
The IMX8 (8-channel electrochemical multiplexer) is suitable for automated experimental throughput, as it enables sequential measurements on up to 8 measurement cells. It therefore offers, with minor limitations, a cost-effective alternative for many applications that would otherwise only be feasible using multi-channel potentiostats.With the IMX8, the throughput of electrochemical experiments in the laboratory can be increased from one channel to a total of eight channels within a reasonable budget. For applications such as corrosion inhibitor development, corrosion testing methods and associated field trials, assessment of coating impedance and the development of chemical sensors, the IMX8 is the ideal addition to the Interface 1010 and Reference 620 potentiostats.
Product Description
The ECM8 (Electrochemical 8-channel Multiplexer) allows you to configure a powerful multi-channel system from a Gamry system, with which you can run the electrochemical direct current or alternating current operations of the active channel on up to 8 electrochemical cells in succession. It is also worth making use of an IMX8 (8-channel electrochemical multiplexer) if you want to carry out measurement sequences repeatedly and automatically or are interested in an increased throughput of long-term experiments.
Each channel of the multiplexer also has “local” potentiostats for potentiostatic control of the inactive channels, e.g. to polarise weakened coating systems on metallic substrates for cathodic debonding experiments in parallel to the active channel using a cross-cut within the available hardware limits of the “local” potentiostats.
The IMX8 (8-channel electrochemical multiplexer) is not suitable for simultaneous multi-channel system experiments with high temporal resolution and a high number of cycles; instead, a system with several active channels (multi-channel potentiostat) is recommended.
