Abstract
An electrochemical gas detector based on an electrolytic measurement cell having a normally solid organic electrolyte. The gas component to be detected diffuses out of the gas chamber at a three phase border (electrolyte-electrode-gas chamber) and there causes a change in the electrochemical equilibrium. As a result in an outer closing circuit a measurable electrical current is produced. The electrolyte consists of an anhydrous organic gel with a very low vapor pressure. The gas chamber adjacent to the three phase border constitutes a partly sealed cavity, which is in communication with the gas atmosphere to be examined via an absorption filter selectively permeable to the measurement component. The length of the cavity is dimensioned so as to be so short that practically no back diffusion of the measurement component through the filter takes place.
