Electrochemical gas detection - with gas-contacting polarisable electrode, non-polarisable and reference electrodes, all in contact with electrolyte

摘要

Appts. for the electrochemical detection of gases has a gas-contacting polarisable electrode, a non-polarisable electrode, a reference electrode and an electrolyte in contact with each of the electrodes. The polarisable electrode and the reference electrode are connected in an almost nonconducting path, and the polarisable electrode and the nonpolarisable electrode are connected electrically via a current detection path. Appts. is simple to use and install, and shows good stability and sensitivity. Detects and measures a wide range of gases, e.g. O2, CO, SO2, N oxides oxides, HCHO and alcohols.
