Working Principle of Nutech Continuous VOCs Monitoring Systems

The ambient air enters into the sampling unit of the continuous monitoring system at a constant flow rate. The VOCs are enriched and pretreated by low temperature trap, and then separated by gas chromatography through thermal desorption and detected by hydrogen flame ionization detector (FID) or mass spectrometry detector (MS). Therefore, the concentrations of total hydrocarbons (THC), non-methane hydrocarbons (NMHC) and each VOCs species are obtained.
