ABSTRACT:
The sensitivity and, especially, the selectivity of a polarographic device can be increased by using an ion selective electrode as the working electrode in the electrochemical cell. The cell is a high sensitivity gas detector which is reliable in operation and which is particularly suitable for use in the field of environmental protection. Especially silver/silver iodide electrodes used in various electrolytes are particularly suitable for detecting hydrocyanic acid, phosgene and hydrogen sulphide.
