MULTICELL AMMONIA SENSOR AND METHOD OF USE THEREOF

摘要

Disclosed herein are methods of sensing NH<SUB>3</SUB> in a gas and sensors therefore. In one embodiment, a method of sensing NH<SUB>3</SUB> in a gas comprises: contacting a NOx electrode with the gas, and determining if a NOx emf between the NOx electrode and a reference electrode is greater than a selected emf. If the NOx emf is greater than the selected emf, a NH<SUB>3</SUB> emf between an NH<SUB>3</SUB> electrode and the reference electrode is determined. If the NOx emf is not greater than the selected emf, a NH<SUB>3</SUB> emf between the NH<SUB>3</SUB> electrode and the NOx electrode is determined.
