The problem was how to locate small leaks in chemical plants where a combination of different substances is present in the background. For this application a gas detector was requested which could detect the target gas at ultra low levels, without responding to other gases.
The idea was to use an electrochemical cell as sensor. This sensor technology will only respond to substances producing a non-soluble salt with the working electrode material. It will not be affected by humidity, hydrogen, or hydrocarbons. To keep the sensor electrically neutral and to stimulate the electron flow, the counter electrode is kept
