Verfahren zum Nachweis von Kohlenwasserstoffen und Kohlenmonoxid

摘要

An apparatus and a method for sensing hydrocarbons and carbon monoxide in a measurement gas, e.g., the exhaust gas from an automobile engine. A solid state electrochemical oxygen pumping cell (10) adds oxygen into the apparatus which contains a solid state combustibles sensor (19) for sensing the hydrocarbons and carbon monoxide. The oxygen may be obtained from ambient air or by dissociation of gasses like water present in the measurement gas.
