Gas Detectors Are Widely Used to Detect Leaks and Monitor Methane ConcentrationsCommercially Available Gas Detection TechnologiesInfrared Sensor (IR Sensor) Is The Technology of Choice For Methane DetectionEdinburgh Sensors Gascard Ng For Reliable Gas DetectionReferences and Further ReadingA nondispersive infrared sensor (NDIR) typically consist of an IR source, a sample chamber, a light filter, and an IR detector. Typically, a second chamber containing a reference gas runs in parallel to the sampling chamber. IR light is directed through the atmospheric sampling chamber to the detector. The methane gas in the sampling chamber absorbs light at specific wavelengths. A filter in front of the detector blocks out light that is not at the desired wavelength, so the detector measures the attenuatio…See more on edinburghsensors.comEMC: Continuous Emission Monitoring Systems | Air Emission ... and Guidelines. A continuous emission monitoring system (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission limitation or standard.
