The system features are as below:
1. Double-pump negative pressure injection design, fast gas update speed, high response speed of gas path, stable injection speed of analyzer, simple structure of gas path, improving the repeatability of the whole system.
2. Inert materials are selected for sampling pipeline and flow path devices to reduce sample adsorption and high data reliability.
3. The system has the function of automatic purging, which can automatically remove the dust on the surface of the filter core and extend the service life of the filter core.
4. The auxiliary gas and carrier gas path adopts EPC to automatically control the gas flow, accurate control, convenient operation, and high-precision instrument measurement.
5, hydrogen generator with liquid level detector, pressure sensor, can achieve automatic water filling, water shutdown, FID flameout automatically stop gas production, the whole system with FID flame extinguishing alarm function, to ensure the safety of the station.
6. The system interface can directly display the average pollutant concentration and hourly discharge in the first hour, with intuitive data for users' reference.
7. It can be customized according to users' requirements to measure the total emission (non-methane total hydrocarbon) while taking into account characteristic pollutants (benzene series, alcohols, lipids, etc.).
8. Through precise control, the analyzer can realize accurate use of various small gas volumes. In addition to the carrier gas, nitrogen is used in high-purity bottles.
