Product Details
The ECM8™ is an affordable way to expand the throughput of your lab. Experiments can be sequentially multiplexed on up to 8 channels. The ECM8™ is ideal for corrosion inhibitor testing, EIS evaluation of paints/coatings, monitoring of field probes for corrosion tests, and chemical sensor development.
Key features include:
- 8-channel for sequential measurements
- DC and AC experiments
- Industry standard multiplexed experiments
Overview
The ECM8™ Electrochemical Multiplexer partners with a Gamry Potentiostat to convert a single potentiostat into a powerful instrument suitable for sequential multichannel operations. It allows you to sequentially take measurements on up to eight electrochemical cells. The ECM8™ Multiplexer is great for automating repetitive experiments, and for increasing throughput on long-term experiments where data can be taken periodically. Each of the eight Multiplexer channels also incorporates a "local" potentiostat to polarize the sample when not participating in the electrochemical experiment. The ECM8™ is not usable for simultaneous multichannel experiments across multiple cells. For simultaneous multichannel experiments see the multichannel potentiostat.
*Note that EIS through the multiplexer is limited to 100 kHz

Great for scaling up constant-potential microbial fuel cell studies
Rating: 5.0
Organization: Yale University
Application Area: Maintain potential for studying multiple microbial fuel cells in parallel
"Maintaining constant potential is critical for growing microbial communities on electrode surfaces. With its eight channels, the ECM8 Electrochemical Multiplexer has allowed us to us to scale up our experiments and study multiple fuel cells in parallel with only one potentiostat. We've worked with several people at Gamry and they all have provided top-notch service during instrument acquisition and after the sale. Instrument set-up is easy and the software is intuitive to use."
