The Thermo Scientific 5800 online gas chromatograph utilizes the principles of gas chromatography coupled with a flame ionization detector (GC-FID) to instantly monitor not only Total Hydrocarbons (THC) and Non-Methane Hydrocarbons (NMHC) in gaseous environments, but also specific VOCs.

Monitorable items include:< ;/p>

A Non-Methane Hydrocarbons (NMHC)

B Benzenes such as benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, isopropylbenzene, styrene, etc.

Customized solutions, such as ozone precursor substances (PAMS) and special requirement monitoring substances such as methanol, propanol, etc.
