【Product Introduction】Online Monitoring System for Volatile Organic Compounds at Pollution Sources (FID)

1.Online Monitoring System for Volatile Organic Compounds from Pollution Sources

Product introduction: 

The online monitoring system for volatile organic compounds in pollution sources consists of three basic parts: volatile organic compound monitoring, exhaust gas parameter monitoring, system control and data acquisition subsystem. It can monitor methane, non-methane total hydrocarbons, benzene series and some halogenated hydrocarbon gas organic pollutants in the exhaust gas, as well as parameters such as temperature, pressure, flow, humidity and oxygen. It is suitable for monitoring toxic and harmful organic gas emissions from complex environmental processes such as industrial or chemical areas. This analysis system and instrument adopt international advanced technology, with stable and reliable performance, high degree of automation and wide detection range. High-quality hardware and highly integrated intelligent industrial computer processing software enable the system to meet the stringent requirements of real-time monitoring.

Parameter principle：

Method principle: Gas chromatography

System composition: sampling and pretreatment system, non-methane total hydrocarbon monitoring unit, flue gas emission parameter monitoring subsystem, data acquisition transmission, processing subsystem, gas source auxiliary device, etc.

Monitoring factors: benzene, toluene, xylene, non-methane total hydrocarbons, temperature, pressure, flow, humidity, oxygen content

Range: 0~100/1000/10000ppm (optional)

Product features：

（1）Using high sensitivity FID detector；

（2）Can simultaneously analyze various gases such as total hydrocarbons, methane, benzene series, etc.；

（3）The gas path is heated throughout to ensure that the gas does not condense, and there is a back-blowing gas path to eliminate other interferences and ensure data accuracy.；

（4）Unique chromatographic column switching and combination technology, advanced modular amplification system, high integration of instrument circuit, modular design, and extremely high operating stability；

（5）The instrument has various functions such as power-on self-check, power-off protection, automatic restart, automatic calibration, etc., ensuring the high sensitivity, high stability and high repeatability of the whole instrument.

（6）The calibration, analysis, real-time display, and maintenance of chromatographic components can be completed through a simple interface.

 

2.Continuous automatic monitoring system for ambient air non-methane total hydrocarbons

Product introduction:

 The continuous automatic monitoring system for non-methane total hydrocarbons in ambient air meets the monitoring requirements for air pollutants in the factory area, factory boundary and surrounding areas. The system consists of a sampling main pipe, a pretreatment unit, an analytical instrument, a hydrogen generator, a zero gas generator, an air compressor, meteorological parameters, a dynamic calibrator, an electronic control unit, etc. It uses a cold trap enrichment direct measurement method to monitor non-methane total hydrocarbon organic matter. It has the characteristics of low detection limit and good repeatability, and is suitable for industrial parks and regional non-methane total hydrocarbon monitoring.
