Carbon Monoxide Sensor CrossSensitivities Alcohols, VOCs ...

MSA XCell Sensor (electrochemical) Given enough residence time or high concentrations, most hydrocarbons and VOCs eventually break through filters and can also cause positive sensor response. These gases or vapors tend to be caught in the filter and can saturate the filter before desorbing over time. As a result, after exposure to a hydrocarbon or VOC, a sensor may need time to stabilize and ...
