Flame ionization detectors (FID)

The FID 22 m NMHC  (mobile variant in a portable case) and FID 22 NMHC  (rack variant) analyser is used for continuous monitoring of the content of hydrocarbons (THC)/ Total Organic Carbon (TOC), Methane (CH4) and Non-Methane Hydrocarbons (NMHC) in gases from industrial plants (emissions) or environments (immissions). 

The sample gas is extracted at the measuring point and passed through the analyser (extractive measurement). 

A flame ionization detector (FID) is used to measure the hydrocarbons (THC). A second sample stream is fed with sample gas via a catalyst and the methane concentration is calculated (CH4). The NMHC value is calculated from these two concentration values.
