Basic knowledge points of non methane total hydrocarbon online monitoring system

Source: | Release time:2022-11-14 | Share:

The online monitoring system for non methane total hydrocarbons in ambient air/fixed pollution sources adopts negative pressure sampling with a sampling pump. The environmental samples pass through the atmospheric sampling manifold and then enter the NMHC gas chromatograph for online monitoring of non methane total hydrocarbon content in the environment through gas chromatography (FID method) technology.
