The challenges with electrochemical NO2 sensors in outdoor ...

23/07/2018· Interfering gases and cross-sensitivity. In a perfect world, an electrochemical sensor would only respond to the gas it is targeted to monitor. A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some …

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs & Hydrogen Technical Bulletin Cross-sensitivity to gases other than the target gas of interest is a common sensor characteristic, especially among electrochemical sensors. Cross-sensitivities are limited as much as possible by MSA sensor design and filters; however, some key interactions still occur. CO sensors do have some inherent ...

Introduction to Electrochemical (EC) Gas Sensors

SGX electrochemical sensors detect gases by producing a chemical reaction between the gas and oxygen contained in the sensor. This reaction produces a small current, which is proportional to the concentration of the gas present. The sensor is, in effect, a type of fuel cell. Reactions occur on two electrodes which when combined together produce the sensing process. These electrodes comprise ...

A Planar Electrochemical Carbon Monoxide Sensor | Semantic ...

This paper reports on a planar electrochemical CO sensor, comprised of three electrodes (working, counter and reference) on an alumina substrate and a cast Nafion film on them. The working and counterelectrodes were made with Pt, while the reference electrode was made with Au. The response was studied with both cyclic voltammetry and constant potential amperometry.

Abstract A solid-state planar electrochemical carbon monoxide sensor was built and studied. The sensor features a planar geometry of the electrodes (working, counter, reference), where all three electrodes are located on the same side of a substrate. The electrodes are covered by the CO-semipermeable proton-conducting polymer film. The sensor shows characteristics of a practical-use …

01/08/2018· The response of an electrochemical gas sensor to gaseous species, other than the measurand, can be thought of as a cross-sensitivity. Since ambient air is a complex and variable matrix it is essential to quantify any cross-sensitivities and develop strategies to remove those signals before reporting a mixing ratio. In this study the cross-sensitivities of the sensors to five common co ...
