Abstract : A two-terminal electrochemical cell was used to detect trace amounts of an oxidizing agent in air. An investigation of the cell's electrical parameters was made while the cell was in uncontaminated air, and while exposed to chlorine or nitrogen dioxide. An equivalent circuit was obtained. The cell, without any external power or circuitry, can detect concentrations below the threshold limit values for chlorine and nitrogen dioxide. The cell output can be increased by passing a small DC current through the cell. This current also improves the cell's recovery time. (Author)
