For measuring: Total hydrocarbons (THC) and methane (CH4)
FID OEM Sensors
The TRACE-GAS FID OEM sensor is based on flame ionization detection and is designed to measure total hydrocarbon concentration (THC). In the dual version, simultaneous detection of the methane content (CH4) in the sample gas is possible. This is done in a second combustion chamber, for which a thermal cutter is used to remove long-chain compounds. This will allow the determination of the content of non-methane hydrocarbons, which is relevant for various applications.
The sensor combines robustness and high sensitivity, which makes it significantly superior to alternative sensors for measuring organic hydrocarbon compounds, such as thermal conductivity sensors. This is not the only reason why FID sensors are increasingly used in conjunction with gas chromatographs (GC).
