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
