METHOD AND APPARATUS FOR SENSING MOLECULAR GASES

摘要

A method and apparatus are provided for the quantitative sensing of molecular gases. The apparatus comprises a gas-sensitive measurement electrode (4,6), a series of solid ion-conductors including at least a salt ion-conductor (10) and a ceramic or glass ion-conductor (12), and a reference electrode (14, 16). The cell potential generated is a direct function of the pressure or concentration of the molecular gas to be sensed.
