IMX8 Electrochemical Multiplexer

Eight-channel electrochemical multiplexer

Expands a single potentiostat across eight channels, sequentially multiplexing DC and AC experiments.

What it does
  • Sequentially multiplexes experiments across up to eight cells
  • Turns a single potentiostat into a multichannel instrument, rather than replacing it
  • DC and AC experiments, using industry-standard multiplexed methods
  • Built for automating repetitive work and for long-term experiments sampled periodically
For applications including
// Overview

The IMX8™ Electrochemical Multiplexer is an affordable way to expand the throughput of your lab. Experiments can be sequentially multiplexed on up to 8 channels. The IMX8 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

Product Details

Overview

The IMX8™ 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 IMX8 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 IMX8 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
