Cy-vocs-05 volatile organic compounds

(non-methane total hydrocarbon, benzene series) online monitoring system

VOCs on-line monitoring system was developed for the discharge outlet of organic waste gas in petrochemical, chemical, printing, spraying and coating industries.The product design conforms to the national standard and EPA standard, which not only meets the demand of VOCs pollutant discharge charge, but also meets the scientific research needs of meteorological monitoring, environmental air quality monitoring and other fields.

Product features

The analytical method was consistent with the standard method, and gc-fid method was used for detection.

High temperature sample transmission in the whole process, high temperature FID detection, small sample loss, more accurate measurement;

Continuous operation free maintenance design, start-up automatic cycle operation, real sense of online analysis;

Full thermal flow path design, can reduce the sample loss, no moisture condensation, suitable for high temperature, high humidity and weak corrosion conditions;

The single cycle time is less than 90S, ensuring real-time monitoring;

Single cycle can realize the accuracy quantitative analysis and detection of non-methane total hydrocarbon and benzyl, toluene and xylene.

FID detector automatically relates to hydrogen after flame extinguishment to ensure system safety.
