With most sensor types, the sensor itself is directly exposed to the gas, often causing the sensor to drift or die prematurely. The main advantage of IR instruments is that the detector does not directly interact with the gas (or gases) to be detected. The major functional compo nents of the analyzer are protected with optical parts. In other words, gas molecules interact only with a …
