Why is hydrogen such a big issue for CO sensors? | GfG ...

Many CO sensors also show a significant response to nitric oxide, (NO). CO sensors also respond strongly to acetylene gas. Since the internal filter does not absorb acetylene, the sensor shows a very strong and immediate response to this gas. GfG Technical Note 2019, “G460 and Micro IV electrochemical (EC) toxic sensor relative response ...

A Molecularly Imprinted Electrochemical Gas Sensor to ...

Two electrochemical sensors have been fabricated to sense BHT in the air at ppm and ppb levels. The graphene sensor was tested at ppm level and the graphene-Prussian blue sensor was tested at ppb level. BHT was detected at a very low concentration, less than 20 ppb, the target range for sensing it in the exhaled breath of Alzheimer’s patients. The developed electrochemical sensors exhibited ...
