Home > Chemical > Application > Emergency Response > Electrochemical Detection (EC)

Electrochemical (EC) detectors detect chemicals in the gas phase by measuring changes in current across a target-specific electrode. When a target gas contacts the electrode an electrochemical reaction takes place, producing a change in current. A variety of EC sensors and detectors are available for identifying gases such as HS2, CO2, TIC/TIMs, explosives, and other chemicals of interest.

Most EC-based detectors can be configured with sensors for specific targets. Most units can detect one to five gases simultaneously. The most promising electrochemical systems use broad-response sensors capable of detecting multiple gases simultaneously.
