A novel carbon dioxide gas sensor based on solid ...

Feb 10, 2003· A planar bielectrolyte type of CO 2 gas sensor based on Nasicon and Na β-alumina solid electrolyte pellets with BaCO 3 –Na 2 CO 3 (weight ratio 44:56) as the auxiliary phase was fabricated. The sensor had good response to CO 2 over a wide range covering 6 ppm to 100%. The Nasicon/Pt interface was sensitive to oxygen, while auxiliary phase applied at low temperature on the sodium rich …

Surface Plasmon Resonance Sensor for Dissolved and Gaseous ...

We describe a novel kind of sensor for carbon dioxide. It is based on surface plasmon resonance (SPR) and a polymer blend that is capable of fully reversibly binding carbon dioxide. The interaction results in a change in the polarity and refractive index that can be detected via SPR. The sensor responds with high specificity. The method is simple and, unlike previous ones, enables continuous ...
