Online Vocs Gas Chromatography Fid Non-Methane Total Hydrocarbon Continuous Emission Monitoring System Gas Analyzer
>>Overview
Used for real-time concentration online monitoring of volatile organic compounds (VOCs) emitted from industries such as petrochemical, spray painting, injection molding, coatings, printing and dyeing, pharmaceuticals, electronics, and automotive manufacturing.
The system uses advanced GC-FID+high-temperature complete extraction technology, capable of measuring multiple parameters including methane, total hydrocarbons, non-methane total hydrocarbons, temperature, pressure, flow rate (flow), O2, humidity, and can be expanded to measure benzene series or other characteristic factors.
The sample gas passes through a dust-removal probe and is heated by a trace-heating tube before entering the high-temperature chromatograph for analysis, effectively preventing sample loss during collection and analysis. It offers excellent stability for data upload and maintenance.
>>Feature
1) The core instrument uses imported multi-port valve design with no dead volume, ensuring measurement precision and accuracy.
2) Equipped with a high-sensitivity detector and low detection limit.
3) Automatic fault recording for easy maintenance.
4) Automatic hydrogen gas source cutoff in case of flameout or hydrogen leak.
5) Expandable for additional monitoring factors.
